In Japan and North America, Monster Hunter Tri is a Capcom game, developed, published and distributed by the company. But in Europe and Australia? It's now Nintendo's problem.
The announcement was made earlier today by Capcom, who say that while they'll still technically be acting as publisher, Nintendo will be "responsible for the sales, marketing and distribution" of the game in Europe and Australasia.
It'll be out in April. Expect to see a lot more marketing for the game than you otherwise would have. Oh, and maybe one or two of those black Wii/Monster Hunter Tri bundles (up top), too.
