The trailer brought screaming back how whiny Bilbo was early in the book though. *shudder*
Though, that makes it fortunate that they'll likely truncate the early, less-exciting parts of the book.
What we'll DEFINITELY see a lot of is mirkwood. That's where Legolas' cameo is, so you can be certain they'll want to make it big.
The scene with the troll statues in LotR was only in the extended edition of the movies, so they may choose to cut that out from the shorter version. Though that'll be a shame, since it's a great story.
You'll definitely be seeing Riddles in the Dark. And you can expect the final battle and the part with the dragon to both receive way more than they deserve.
Thinking about it, I kinda feel like it should be split into two movies. Part one could easily end when Bilbo emerges from beneath the mountains, with the ring. Part two could have picked up with him reuniting with the group.
I guess the real issue is that would make part I way less exciting.
WAIT, it IS being split? I thought it wasn't. Awesome! Because I REALLY don't think 3 hours would have been enough.
