Developing new SPU enable game engines takes some time. MGS4, FF XIII and GT5 should all be 1080p.
Some new GT5 screenshots (720p):

IMO Ratchet & Clank: Tools of Destruction is awesome in 720p, but Insomniac made major advancements (PS2 engine => PS3 game engine with 10-20 SPU usage of 5 SPUs for Resistance 1, now nearly the whole game engine is running on 6 SPUs for Resistance 2).
