"sorry to burst your bubble, but AAA games are mostly developed for consoles in mind first, then ported to PC. so chances of games utilizing more than 4 cores in the near future? VERY SLIM."
Theoretically, though, the fact that the consoles have an 8 physical core cpu (well, 6 or 7 cores actually available to game programmers) should mean that we'd see better multithreading on game engines, but to this point its been few and far between for the well optimized port.
Regardless, the whole problem with Bulldozer/Piledriver/whatever was that it had competitive or superior multi-core performance to its intel competitor, but Intel just obliterated them in single core performance, which definitely helped Intel for gamers. Now, it appears with Ryzen, that gap is gone. So, what we have is a product lineup on one side (AMD) in which you can get a low-priced 4C/8T cpu that can match Intel's best for games, *AND* if DX12/better multithread porting takes off, you can upgrade to a much cheaper 8C/16T Ryzen on the same mobo/chipset to cover that potential situation.
The problem for Intel here is that if more than 4 physical cores becomes helpful for games or mainstream apps, they have nothing beyond their 4 core cpus for their mainstream consumer chipsets (Z270 and the like), and their 2011-socket 6+ core cpus require a completely new mobo, plus also being much more expensive than the Ryzen equivalent. (e.g. the 6900K vs 1800X).
Intel isnt stupid though---I would expect some massive price cuts shortly.
