Of course, the proof of this concept is in the pudding, namely how fast ATI can release profiles for new games after they hit retail shelves. If they can't release these profiles within a day or so of a new game hitting user's hard drives then the old complaints about driver support will continue, to be assuaged only by allowing users to create or edit their own profiles - Something which ATI hasn't written off as a feature to be added in the future incidentally; rather, they're simply confident that it won't be required at this present time. Only time will tell, and we'll certainly be keeping an eye on how expedient ATI can be at updating their profile list over the coming months.
Doesn't storing Crossfire profiles in un-obfuscated XML imply that users are basically gaining full control over them? If AMD proves an inability to to release profiles in a timely fashion, can't a user-provided app take over that function?
PS: I recently had a run-in with some Mobility Radeon driver issues on a 24" iMac in BootCamp. It will be nice to have them a little more idiot-proof.
