The reality of the PS2 is that it it has arguably the greatest selection of games any console has ever had, ever and it did that with arguably the worst specs overall.|
Since we have almost nothing to go on with the PS4 apart from some vague information about it's specs and even less information about the next xbox naturally people are talking about things we do know and make wild speculations on the unknown based on "educated" guesses. Which means inevitably there's going to be some discussion about the memory bandwidth of the PS4 simply because there's not a lot else to talk about.
But lets go down your route lets talk about games on the next xbox, ummmmmmmmmmmmm we don't know any. Lets talk about games for the PS4 well aside from a few brief demos and some videos of others we don't really know much about that either.
So were back to the few stats on the PS4 we can actually talk about.
