It is not about doubting what the guy said, it is about knowing with absolute certainty that what the guy said is complete and utter bullshit. How cpu and gpu interact in the past, present and future is a difficult subject I'm not going to lecture on. There was the recent Build conference and within that, a talk about XBox One hardware by an ms guy who knows his stuff. He mentioned some very intereting and new facts that have not been covered yet in any forum I've seen. Again, too technical, but there was a point that is very important to mention concerning DX12 and magical speed increases: That crucial part of DX12 ("Draw call hell") was already in the XBox One os segments when the console launched. There will only be some speed increases if a) the software used a "detour driver path", or better: the easy driver path and b) the cpu was choked by the software. I have not heard about anyone complaining that their software choked the Jaguar cores so b) is not likely to be a source of speedup.
The speed will only increase if developers will examine their esram/ddr ram use down to the last kByte (essentially foregoing many "recipes" ms offers in their sdks) and/or use some obscure future DX12 extensions. Even then, I don't expect more than a few % of improvement per year. Then again, LibGCM on the PS4 may offer similar improvements over time so we'd still be at a stalemate as far as speed is concerned
