We might get a new trailer next week because,that event coming up on the 4/27-4/28 says that there is going to be alot of major announcements on MH4.Besides that,a contest is going to be held to see who can kill the Infected Tigrex and some special guest will also be there.If you manage to kill the Tigrex you get special prizes.

Also if you ask it's the same demo from TGS and Jump Festa.
