Todays PS4 stuff was super-interesting, but not enough to push me into a day-one, hell even a year-one purchase. If you ask me it's never been that great am idea to get a console it's first year, with rare exceptions most systems don't see any really great, exclusive games until year two or three of their life. The only semi-recent example of a great, must-own launch game was Halo. Before that, Mario 64, I guess? Hell, I didn't bite on the PS3 until holiday 2009, and that was because of Uncharted 2.
Maybe there'll be some real barn-burner shit at E3, but as of right now I am very much in the camp of 'meh' on the next generation of systems. The Wii-U is a total non-starter for me, and the only game that would have pushed me to get one (Rayman) is coming to 360 and PS3. I'm way past the point of burnt-out with the regular stable of Nintendo exclusives with the exception of Metroid, but I doubt we'll see anything like the Prime games ever again, so I'm not holding my breath. So far based on what (admittedly little) we've seen from Sony I'm starting to get that way with the PS4. Everything they showed today either I don't care about (Killzone, Deep Down) or I can get on PC or current-gen systems (Diablo 3, Destiny, Watch Dogs). I'm sure The Witness will be interesting, but not $400-$600 interesting, and that's the whole vibe I got from everything today.
