RedHat has bought a Microsoft license to be able to boot on UEFI hardware with Microsoft key.
The problem of course is that Fedora will perhaps be tied to Microsoft's Secure UEFI efforts in order to enable Linux on new hardware. The bigger problem would be if Secure UEFI wasn't dealt with and Linux wouldn't run on new hardware at all.
I respect Garrett's position, though I have another solution.

Don't buy, UEFI Windows 8 hardware Seriously. Why pay the Microsoft tax? Build your own machine, motherboards from computer stores (newegg etc) will have lots of options and you won't need to bother with the Window 8 pre-load either.
Looks Like the only Linuxes around by this time next year will be Fedora/Redhat and Suse and maybe Ubuntu with its own hardware.
