I think the fact that MHTri (a game not really known across the West) can boost sales by a nice margin should show that SW (and third-party, in that regard) can easily push the Wii U up the sales charts. If the Wii U got an even bigger name, then it would be even more impressive. (I think the MHTri boost is just a bubble, though.)
It's all relative with the Wii U right now. Bigger name = Bigger boost.
Question is with all the hype over the PS4 and nextbox, can it build itself a name? Personally this is where I think Ninty dropped the ball that it can't flash it's goods and show gamers enough of something different and will get lost on the Nintendo shelves in most game stores.
Is there anything you are expecting to boost it's rep? Price cut, game releases?
