Well, if the budget's bigger, it will.
Thats why the first had very frenetic fight scenes.
Actually, those types of shots would be much harder to do than ones that are more steady. Camera tracking and set reconstruction is hard, and not to mention all the stuff they have to do on-set.
If they're following the leaked outline from a while back (which it seems like they are, roughly), then there's a lot more robot time in this one so that's where the money's going.
