USB Front Case Panel connections compatible with USB 3.0?

If the motherboard is compatible with USB 3.0, will those connections work with the USB 2.0 front panel connections on the case giving USB 3.0 speed or will the entire case need to be upgrade? I ask this for those who buy a PC case with USB 2.0 front connections just a month or so before USB 3.0 hits.

I think theoretically they should work as it shares the connector and is designed to be compatible.

No.
Although USB 3 is going to be backwards compatible with USB 1/2 devices, I understand it will use an additional four data wires with USB 3 devices. It will also have different receptacles than the current USB 1/2 and send more power through the lines. As such, a case receptacle designed for USB 1/2 will not be compatible with USB 3.

*USB 3.0 receptacles are compatible with USB 2.0 device plugs for the respective physical form factors. However, only USB 3.0 Standard-B receptacles can accept USB 3.0 Standard-B device plugs.

*The protocol uses Dual-simplex, over four additional wires, differential signaling separate from USB 2.0 signaling (thus six wires total) to achieve the full Superspeed 5.0 Gbit/s

*The bus power spec has been increased so that a unit load is 150mA (+50% over USB 2.0). An unconfigured device can still draw only 1 unit load, but a configured device can draw up to 6 unit loads (900mA, an 80% increase over USB 2.0). Minimum device operating voltage is dropped from 4.4V to 4V

If one is buying a new PC case now, what would be your advice? I am buying a new case because I really need one. How would I go about changing the front USB receptacle and wiring to accept the new format (besides getting a new motherboard or having an expansion slot).

I just conducted a search at newegg for USB 3.0 devices. The search drew a blank. Are there any devices using USB 3.0? What about USB 3.0 headers on motherboards? I knew USB 3.0 was coming but haven't read very much about it.

I was also looking at specifications for computer cases. I did not see any case specifications indicating USB 3.0 connections. Actually, the specifications only indicate the front panels have USB connections but do not specify which version.

The wikipedia article says USB 3.0 consumer devices are not until 2010 and no drivers have been released yet.
