Here's some of the changes for the weapons,for people who didn't see it on the videos.

http://trinfo.jp/blog-entry-856.html SnS,Lance and GS

http://trinfo.jp/blog-entry-857.html Longsword and Gunlance

http://trinfo.jp/blog-entry-858.html Switch Axe

http://trinfo.jp/blog-entry-859.html Hunting Horn

From what I found on these,the SnS has hop back similar to the Lance or MHFO SR SnS,the Greatsword(like we saw alot of times)has a new charged uppercut,Longsword has new attack after jumping back,Switch Axe,in Sword Mode,has similar combo to its Axe Mode counterpart,and Hunting Horn may have a new combo.That's what I could find but,their is most likely more.

Also,on 859,did the ground rise?
