I picked it up last week, I really like it so far.

What I like:
Skating ramps and vert is a lot easier.
New tricks are really cool.
The animations are a lot smoother but looks like the environment have slightly decreased in quality.
Skitching rides behind cars is great.
Pulling objects around is cool if you want to make your own gaps.
Loading times improved from skate 1, especially when you put down session markers.
Overall it's a great skateboarding game.

Dislikes:

In Career mode some of the voice actors get really annoying, especially when you're trying to achieve a goal and you keep missing. They just keep repeating their lines.
Walking around off your board is good but controlling your character is kinda sketchy, he doesn't move around very well.
Some glitches like being part of the geometry or taking a serious bail 10 feet in the air when you just hopped on your board.


I think that's it so far, I'm sure I'll discover more pros and cons as I keep playing.
