It comes out on September 14.

Anyway I would say this is the final trailer but, going by most of the new games that start a generation, I say we may have one more trailer because, when Tri was released we got this instead of the intro but, than with the rest of the 3rd generation we got intros last instead of trailers. So it could go either way with MH4 since they haven't shown their Powerhouse yet.

Also Famitsu released this along with Goa Magara, http://mh3neko32.blog83.fc2.com/blog-entry-2340.html It pretty is giving the dates for each issue with MH4 info. The large one on 8/29 is major info on the game so, we could see some old and new monsters. The last one is a guide on the game.
