For consoles only:

MGS V > The Division > Infamous SS > Forza 5 > Killzone SF > Ryse

Metal Gear Solid V, The Division and Ryse for me.

sure, as example here

Mario Kart 8 and Witcher 3: Wild hunt. Won't bore you like Crytek too imo.

i don't have a winner but (including probably games running on a pc)

the witcher 3, the division, forza 5, battlefield 4, ryse, infamous and killzone.

not from a pure technical perspective but really great to look at as a whole : mario kart 8, a really great looking game.

The Division. The only game which really stood out for me at E3, in terms of graphics. Killzone SF and inFAMOUS are decent as launch/window titles but aren't THAT impressive to me.. and other games - MGSV, BF4, FFXV, Witcher 2 (as good as they looked) are mostly just an improvement on last gen and roughly on par with higher end PC graphics - not nearly enough to really "wow" me. A lot of these upcoming games are going to be cross gen titles with current gen specs in mind (assets) so it'll be while before devs can show something truly next gen.

If I had to put my money on this though, It'd probably be David Cage's next game on PS4 - assuming it matches the fidelity shown in the 'Dark Sorcerer' demo.

Killzone Shadow Fall game play

For me inFamous: Second Son

InFamous:Second Son, Killzone: Shadowfall, MGS5, the Division.

Love the art style of FFXV though. :)
