I do feel people need to scale down their expectations a bit. Yeah, it has higher specs, but look at how PC games are with even higher specs, they aren't that much of a jump from the 360 and PS3
The PS4 and new Xbox will be a hard sell outside of the very core gamer, and that's coming from someone who has all the consoles atm.
I really am intrigued about how this conference will go, but the stuff on Kotaku has me worried with price, subscription requirements etc. I just hope Sony manage to impress with something cool
