Wow, the 3DS version of Monster Hunter sold over 500,000 copies in its first week on sale. Something the Vita could badly have done because despite their decent efforts, all the wannabes just can't touch the phenomenon that is MH in Japan.
So, over the next few months, that's going to be four to five million gamers all squinting away at HM in 3D that won't be buying a Vita - a serious chunk of Sony's target audience. Even if Capcom does throw Sony a bone with a Vita upgraded version of MH3, the boat is sailing right now and it could take until 2013/14 for Capcom to come up with a proper sequel.
In the week before launch, you have to wonder how much Capcom asked Sony for to keep the game on its handheld. I suspect whatever it was Sony should have paid, because no matter what Nintendo paid Capcom, they just gor their money back.
