lol, you had to watch the whole conference to understand. they were going on and on about audio, some skyrim knock-off, and a bunch of other awkward stuff. by the time Raptr came along, it was like "ok, their version of Nvidia Experience... NEXT!" the presenter also said some things about bringing the community together, and pretty much downplayed Steam in the same breath
basically the whole thing was a disaster up until the point they dropped the Mantle bomb. I know that sounds like typical internet hyperbole, but it really was bad (to be fair, I guess this was the first time AMD did something like this)
we'll have to see how the Mantle stuff works out, but it's definitely already a controversial subject. older PC gamers remember 3dfx's Glide API and all the fragmentation it caused. and how DX was seen as a good thing coming out of that, since everyone could use it
plus it seems they are going in a different direction from Valve and Nvidia. AMD hinted at a Linux announcement, but really didn't deliver (I think they said something about "cross platform", but nothing really specific). and people worry about the further fragmentation that could cause
things in the PC gaming universe have been pretty simple for a minute. the most someone had to worry about was the minimum specs, and maybe if they could use stuff like Physx. but things look like they're gonna get a little more complicated...
