Haven't got to U3 yet, it's sitting on my desk. I liked GOW3, even if the ending fell a bit flat, it was a good way to see the series out. I'd add that devs making games specifically for PS3 also seem to take chanced a bit more and try different genres.
TM is sick, but unfortunately Sony doesn't seem to want to really support it. Vita got in the way and TM's been left behind and not fixed.
Anyways, that's what next gens do, they shake things up.
Sony started off this gen really well, but seems to be faltering and holding back resources as the rest of the company crash and burns. PSN really needs a major redesign, and they need to force some sort of requirements on 3rd party dev's. The experience from one game to another, even 1st party, it way to drastic.
