Below is some of the information I've found...still no word on a release date for the mst hubs. But as of ces2012 the good people at IDT demonstrated a working prototype.

DisplayPort chips IDT, of multi-display output support
- Can also daisy-chain multi-output
Simultaneous output of three strains in the dongle with DisplayPort output of Macbook VMM1300
Held June 3
(IDT) is 3 days, held a briefing session of LSI "PanelPort VMM1300" to allow new multi-display of DisplayPort output eye-DT Limited Liability Company in Japan.
Features of DisplayPort
IDT is focused on, such as receiver / transmitter chip "PanelPort" series, and semiconductor solutions for DisplayPort, VMM1300 becomes the new product. DisplayPort is, has been established as a standard of VESA, along with the replacement of the connection between the display and DVI PC, is aiming to replace LVDS technology has been used in internal digital connection of notebook PC and DVI.
VMM1300 is compliant with DisplayPort v1.1a, HDCP v1.3 and support VESA Direct Drive Monitor, and EDIDv1.4. Voice transmission is not supported. Sample shipments of chipsets has already started, you are planning a full-scale production in August.
At the moment are assumed to be incorporated in to the motherboard / graphics card mainly for PC and PC display. Features, with integrated receiver / transmitter for DisplayPort, DisplayPort output from a strain, that multi-display output of up to three Ru can. At the hub with a chip the same, can be output to three sets of input of one system, not only treated as a display of one of the three, such as the ability to copy the screen output 3 the same screen, display a flexible Ru can. DisplayPort output of multi-display solutions has been the world's first, called it ViewXpand in IDT.
Multi-monitor output, in addition to use with a hub VMM1300, can be displayed, even (cascade connection) link together the display with a daisy chain. Cascade multi-monitor are not included in the standard, incorporated into VMM1300 that preceded the feature in the upcoming version 1.2 of the DisplayPort v.1.1.
Simultaneous output to the display of three strains Also supports three strains of the same screen output The demos use a hub equipped with an input three output VMM1300

Mr. Ji Park general manager in charge of video and display operation of IDT U.S. Vice President, explains the benefits of multi-display with highlighting the benefits of DisplayPort. To introduce such as data by the Fraunhofer Institute IAO "in a production environment you can use the display units 3, 35.5% to improve productivity," and complained of the benefits of multi-display support VMM1300.
In addition, there is another drawback of the graphics card will need to be added, such as power consumption increases in the traditional DVI, DisplayPort in, the system is only one output port, the benefits of such a power can be supplied from the PC side and description. In addition, when used as a USB multi-display display, that there is a degradation of image quality by bandwidth compression is inadequate, and there are drawbacks such as that do not support HDCP, that explains the advantages of DisplayPort.

DisplayPort allows in theory the use of dozens of displays via daisy chaining. It does not matter whether DisplayPort are monitors or other displays. The first daisy chain configurations could Vesa show now in operation.
DISPLAY
Daisy chaining was demonstrated at CES 2012 with a total of four monitors. A notebook display, and three behind-connected monitors are shown. One of the behind-connected monitors had a resolution of 2,560 x 1,600 pixels (WQXGA), two 1,920 x 1,080 pixels (full HD). Theoretically, according to VESA 63 monitors are possible. However, the spectrum of DisplayPort 1.2 is not enough to run as many monitors with reasonable resolution.
According to Vesa configuration examples shown next to the system with sufficient bandwidth demonstrated in front of about two WQXGA displays or four full-HD displays. Who needs more monitors, you must use correspondingly low-resolution displays. DisplayPort at CES was also demonstrated by the way with a 4K display.
The silicon is ready monitors are available in a few months
The necessary components are now ready for daisy chaining, said the Vesa. It took some time, but AMD did, for example, already at the Radeon 6000 generation to point out that the card supports multi-streaming, and so daisy chaining with six monitors. Hardware defect , we were able in our test the Radeon HD 6970 over a year ago not to try. AMD promises but can now be redeemed, as the monitor industry has followed suit.
When confronted, the Vesa pointed at CES on the compliance tests were necessary to ensure that the hardware between the manufacturers works. It is obvious now complete. Daisy chaining has been demonstrated, however, only with modified screens. Huge development boards were still hanging on to the monitors, but correspond to the functionality of the final state.
The hardware should be integrated in monitor design by mid-2012. The Vesa expected especially in the business environment so that customers that implement daisy chain monitors. So then you have an off and an input. These will be labeled accordingly in most cases. While it is possible that a display automatically detects which contact as an input or output is used, however, would mean higher costs, the Vesa. Apple, for example, does this in his Thunderbolt interface Sun It is used both as training as well as input.
Little additional cost for monitor manufacturers, hubs are expensive sometimes only
The integration of DisplayPort is expected to cost just $ 2, as the Vesa estimate carefully. It would be so for many producers, especially in the corporate environment, more investment is negligible. One-off costs for the redesign but would probably do so. For 20-inch low-cost monitors that can be in Germany at prices net of around 100 €, but these are $ 2 a lot, because dealers and manufacturer margins must be calculated in the calculation of production costs.
Due to the expected small number of items, a display port hub is not quite as cheap. It is expected that prices will be the first devices in more than 50 U.S. dollars. The functionality of a hub could also demonstrate the Vesa. An example system via display port hub with three monitors were connected.
They have the advantage of old monitors, whether can be used by the display port or an adapter, DVI or HDMI monitors. It is currently unclear how many ports are passive way. 1.5 watts is DisplayPort currently available. That should be enough to secure a 2-port hub with one input. Maybe even 3-port hub without power supply are possible. The Vesa wants with DisplayPort 1.2a, the wattage in preparation for Mobility DisplayPort but still increase .
Hubs and daisy chain monitors should appear almost simultaneously on the market.
