Anyway my thoughts on the games.
Deep Down - Doesn't look like it'd be my thing at all, looked visually very impressive though.
Destiny - No interest in FPS.
Diablo 3 - No interest in that sort of game.
Drive Club - Certainly my genre and from what we saw it looked like a decent PGR style game but teams/clubs aren't my thing so if that is the only option and there is no straight up single player i'll probably not be interested.
Final Fantasy - Well it was a pretty pointless announcement because we know what their release schedules are like, I'm still waiting for FFX HD. Which was the last FF game I enjoyed so unless the core mechanics are more like that and earlier, doubt i'd be interested.
Infamous: Second Son - I played the first Infamous and didn't like it at all so again didn't really pique my interest.
Killzone see Destiny.
Knack I like these sorts of platform games so it could be good, didn't look anything too revolutionary though. Need to see more.
The Witness Pretty meh, again nothing to set the world alight, just a puzzle game as we've seen for years. Might be fun but yeah, not exciting.
Watch Dogs Certainly looks impressive but as something we'd already seen it was hard to get excited. Gameplay looked good, if a little disjointed in who the guy was and what his aims were/which 'side' he was on.
So yeah overall those few games did very little for me personally, hopefully I see a lot more over the next few months and E3 that are more my thing.

Oh by the way, all the 4k gaming talk has been put to bed, Sony have confirmed what most sane people expected, 4k multimedia yes, 4k gaming no.
