Maybe Resistance, Jak & Daxter, Littlebigplanet and Killzone, although they are arguably A tier.

Definitely Ratchet and Clank, Infamous, Sly Cooper and Wipeout though.

Pretty sure Infamous is A-Tier by now.

I can't comment one way or the other since Infamous is one of the games that has caught my interest for the PS4 but I would suggest to bare in mind that I'm ranking Metroid as "B Tier" in the Nintendo example in my opening post.
