According to Japanese game magazine Game Lab, Nintendo 3DS exclusive Monster Hunter 4 was delayed to summer for a reason other than "improving quality". That reason is apparently that the game is also being developed for the PS Vita. Rumors say (via Game Lab) that the game's getting a simultaneous release on the 3DS and the PS Vita.

Why is this a big deal? In Japan, Monster Hunter is the reason why the PSP was so popular. Having it can make a system.

Game Lab's rumors certainly aren't always correct. It did correctly say God Eater 2 was going to the PS Vita before that was officially announced.

But to be honest, I do not believe that Monster Hunter 4 would get a simultaneous 3DS and PS Vita release. Nintendo, for one, would never allow it. But since Capcom does like multiplatform titles, I would not be surprised if Monster Hunter 4 made it to the Vita in some form or another. Eventually. Now that I believe.

Kotaku is following up with Capcom and will update this post should the company comment.
