I saw a bit of the conference, but I got bored pretty quickly with the "let's hype everything to death" talk and turned it off after about 20 minutes.
I do not like the controller. The dualshock controllers are incredibly uncomfortable and always have been. They haven't redesigned their controllers since the PSX came out. So it's basically the same old thing with a touchpad tacked on the top in a place that will be hard to use...and it uses a sensor bar.
As one of my friends said, "So...is this the Wii U now?"
I just finally picked up a PS3 in November, and I have yet to actually play anything on it - it's joined my former PSP and now my Vita as "Sony systems I never play". Good thing I'm not really inclined to pick up a PS4 - I'll probably wait a few years until they drop down to $200 as well.
