EA have put their top videos here http://www.origin.com/uk/ including the particularly tasty Battlefield 3, SSX and NFS latest vids. A well spent 10 mins watching those.
The Official Sony Blog has a nice few postings, covering PSP -> NGP -> official name = Playstation Vita (daft name, it's a bloody PSP isn't it?), Unchartered 3 and... Dust 514, which looks mighty fine.
Can't be bothered to dig more, add your favs please:
