I doubt "bunnyhopping" would make it to this game, not really needed with the SMART system.
Bunnyhopping is basicly an exploit (just like dolphin-diving); it's always better to be impossible.
Some people will probably manage to get some interesting movement-skills with the SMART-system, but I wouldn't go anywhere near to the point of saying "This is the new bunnyhopping". After all, you won't be able to make like 3 wallhops in a row because after the first you'll probably not have enough momentum left.
Well I can't speak for the rest of the world, but I personally like the cartoonish style. It's a nice break from all the uber realistic graphics that we're seeing in more and more games.
Wait, wait, wait. This is the uber (hyper) realistic graphic style in it's best!
