This week's Nintendo Channel update has been pumped up beyond all recognition, and not because there's a bunch of new stuff to look at. In fact, there's really not that much at all, save for some new No More Heroes 2: Desperate Struggle teasers; however, the inclusion of a brief Muscle March info trailer is enough for us to question whether or not this week's update is on some kind of performance-enhancing drug. We've contacted the appropriate authorities, but in the meanwhile, head past the break for this week's content.
