So that's a reason for me to buy XOne first, as it can bring me more fun.

Fun: something some players forget about gaming reason...

What fun fighting game can I play on PS4 like KI?

Skype engine can be used not only for chat out of gameplay. It will be able to interact with games functions.

Let's wait for Sony to show more. MS announced a lot of servers and every game with cloud use, like Forza 5, Dead Rising 3...

Sony said "wait for greatness". I'm still waiting.

P.S. Gaikai is not cloud processor. It's just for streaming old games. It doesn't improve games.

If they're quite the same, which one brings us more?

PS4's innovation for gameplay: share function, cross chat, central button, and joystick's lights.

Xbox One's innovation for gameplay: share function, smartglass, smartmatch, cloud powered, player recognition, voice control, gesture control, force feedback on triggers, multimidia integration, skype engine.

Which one brings you more?

P.S. Listed is for gameplay only...

@Monsterkillah @ALCHEMISTx24x7 PCs with quite the same configuration of actual Xbox One...

@IanNottinghamX Dev PCs with quite the same configuration of actual XOne... Ryse was 60 fps at Comic Con...

@Warful @Zicoroen @arkhamcity54 No, it wasn't. Announced 60fps at Comic Con.

@arkhamcity54 What games from PS4 are at 60fps? From Xone until now: Killer Instinct, Forza 5, Halo, Dead Rising 3, Ryse, Titanfall...

This GPU clock increase makes a lot with DirectX 11. XBox One can be a very harmonic machine. Quite every game announced comes at 60 fps and improvement may come.
