My ears may be playing tricks on me, but I'm pretty sure the track at the end was a remix of… something… from the PS2 days. It was too short, though, couldn't quite make out what it was…
Anyway, I'm still really excited! Clank gameplay doesn't look too slow from what little we see of it in this trailer, and he's packing heat! Or at least a bomb glove
It looks like they're trying to give each level a unique twist to make it interesting for people who have already played the original game (in Pokitaru's case, it's the giant Plytopus at the end of the regular level section)
Also was that Clank section the part where he escapes the robot factory on Quartu? Definitely seems that way, especially since Victor's trying to catch him. I guess this game will start with a Clank level like ACiT.
And I noticed that the trailer seemed to focus more on Nefarious than Drek… I guess since the game will have a lot more "filler" where they can't really use Drek, they'll just use Neffy… he's probably the main villain, even if he isn't the one pulling the strings.
