I have no clue why Nintendo is so excited about Diablo 3 since it is a very old game. They must have some real Diablo fanboys at Nintendo of America. The dock looks cool though. When the Switch revision comes out I am just going to wait and buy one of the limited bundles.
Just like with Skyrim getting pushed last year, Nintendo wants to create a strong relationship with devs/pubs such as Bethesda & Blizzard which dont have much of a history with them.
It also shows consumers that Nintendo is serious about getting and maintaining support from hardcore western games which is something they have lacked in the past.
When the herd loses its way, the shepard must kill the bull that leads them astray.
