>_< If I have to poin this out again, I'm going to have an aneurism.

Steven, look at this trailer for MH3: http://www.youtube.com/watch?v=LwM4NJvbmBQ It's the first full gameplay trailer from 2008 (a year before the game would release in 2009). Now look at an American trailer from after the game was already out: http://www.youtube.com/watch?v=4XvxNCyUGJk Any graphical differences are extremely minor if even existent.

We can apply this logic here. The first full gameplay trailer for MH4 came out in 2012. The full game is released a year later in 2013. I highly, highly doubt they're going to overhaul the entire graphics engine noticeably in that time frame.
