I'm surprised no one has made a thread about this yet. Why hasn't there been more talk about this game? Its the second major improvement they've added since the series started. The first being underwater battling on Tri for the Wii.

So, it seems the worlds are larger and more open now.

The environment are more destructable.

There is battling on the sides of walls.

You can now jump on monster and attack them while clinging to them.

You can do attacks in the air.

Where have you been? Plenty of talk and details in those threads. The game will contain multiple cities, that was the latest info. But if you think this trailer looks good, check the real sized version, much better:

Oh, I looked but I didn't see any of those. Well, scratch this thread then.

Hasn't that been removed again for MH4 anyway?

Damn! Looks f'n nice, I would like to play this on the Wii U if they put it on there.

Some of the colors are waaaaaaaaaaaaaay to saturated. Looks cool overall dough.

I'm really excited about this game. I hope it gets localized over here. Global launch would be awesome :D
