PS4
Sony is putting a lot of effort in its library.
We know most of their teams are working on NextGen Games and all of them are spread out over a lot of different genres.
You get new IPs with probably interesting concepts and new innovations besides the sequels of their best and well known franchises.
The PS4 architecture is closer to a PC this time like Microsoft is used to do it and its probably the stronger console.So Multiplatform Games should run without any problems and tears from the developers(i don't care anyways cause of GamingPC).
Japanese Developers won't make the same mistake as they did in the beginning of the PS360 Gen.Hard to understand architecture is gone and the PS4 won't release 1 year later.And after this Gen they have seen the money from Microsoft isn't worth to take the risk of getting hate from your fanbase and low sale numbers.They will probably spread out over Sony and few of them on Nintendo.
PSN+ right now is far superior to XboxLive and more customer friendly...I think Sony will keep this up.
At the end i will own all 3 consoles but i will get the WiiU and the NextBox when they are damn cheap.
