To my knowledge, the FCC did actually ban their use since the 700MHz band is being reclaimed by commercial providers and first responders (police, fire, and hospital services) once the DTV transition is complete. If you'd like more information though I'd strongly suggest checking out the following links:

Gah, firefox crashed and lost a nice long post...
Anyway... I think it should be mentioned in here that this is a different issue than the white spaces debate. According to press release on Shure's website.
Wireless microphones and personal monitors may continue to operate in the UHF television band between TV channels 14-51 (470-698 MHz), and in the VHF television band between TV channels 7-13 (174-216 MHz).
In regard to the white spaces issue, it remains to be seen how things will play out with the geo-location database and interference detection systems. I think it is safe to say that the consumer grade products that Best Buy sells will be hit harder than professional grade systems. Simply because of the consumer grade products' lack of frequency choices and good frequency detection/management systems.
If you are planning on investing in wireless systems, it's worth your time to look into which TV stations in your city will be operating between channels 2 and 20. The FCC has said that only "Fixed" white spaces devices may be used in that channel range, and since they operate at a much higher power than the portable devices may not be used on a station that is adjacent to an actual TV station. That means that those adjacent channel frequencies are a great choice for wireless microphones if they want to avoid messing with the white space devices.
