That is a pretty bad sign IMO. What he should have done is put up a benchmark with a 390X, FuryX, 980Ti and Polaris 10/11, shown respective power draw and put a price up. Job done, AMD fans go crazy, shuts down Nvidia's limelight and immediately pauses at least some people preordering the 1080.
Instead the runours and leaked benchmarks are liekly true. Big Polaris gets close to 390X performance with much less power only a small cheap eaisly fabbed chip. That is all the makings of a great GPU for the low and mid-end which Nvidia don't have an answer for yet (Gp106 rumored for maybe September). If priced properly below the 1070 it will sell well. AMD are just left with no response to bigger faster Pasal cards.
I hope I'm wrong about AMD but I just don't see it. The leaked specs and chip size, power consumption, benchmarks and absolutely no rumour of a 300-400mm chip from AMD.
