If this were the case then more people would buy the Wii U or Xbox One as most people keep saying that they're just too underpowered compared to the PS4 =p
However in my honest opinion I don't care which console that is the strongest or has the best specs. Gameplay and games above anything else. I'll most likely end up buying a PS4 by the end of the year as the titles that interests is about to release ^^
All in all I agree with the OP and think that that should be the way to go, rather than just going by pure specs. Good thread
