Well if it did work without implementing crossfire in the drivers the x2 will be a great card no doubt, but personally, I think it still is gonna implement crossfire, and have compatibility issues.
We won't know but that's my guess.

I hope it wont
Cant see any reason for it to need anything other than the driver since they have a chip on board to get the two running together! So fingers crossed that crossfire will only come into effect with a 2nd x2 
. It will be nice having a dual GPU card, Dual core CPU, Dual core GPU, goes together nicely
