Yeah, Ratchet & Clank is what I'm most looking forward to. Second is Spyro 4 and Sly Raccoon (a cel-shaded thief 'em up where you play a bad guy).
Here are some ace (and very hi-res) screenshots of Ratchet & Clank.

Also check
www.gamescreenshots.com; they've got some excellent Jak & Daxter production art, amongst other things. Great place for finding screenshots of existing and forthcoming games.
