Seems a bit early to make a solid prediction for this game. We need to see how good the gameplay is in a contiguous gameplay demo, which form the level design takes (purely level-based, a bit more sandbox-y, fully sandbox, or some other point in the continuum), and some other details. The game has gotten good exposure, with the trailer doing significant numbers on YouTube. That doesn't mean sales directly or anything, but it does mean a lot of people are looking at it. Whether they will ultimately buy it will depend on the quality of the game and how Nintendo handles the release. From the early stuff we've shown, this game seems to have some good things going for it, so I definitely wouldn't rule out a 5M or higher performance. But I wouldn't feel at all confident saying whether it will or won't at this point in time.
