I really wasn't planning on picking this up, but all this new info's definitely changed my mind.
I was a big fan of the Ratchet & Clank games on PS3, but didn't really care for the first one when I played the trilogy re-release. It just felt really primitive, and tough to play compared to the later games. It's great to hear that they're updating the whole thing from the ground up, and that it's basically a new game all-together.
