As Bender would say, "Are you familiar with the old robot saying 'does not compute'?"
Calling Super Smash Bros. a "niche" or "obscure" title doesn't make much sense to me. The series is one of the more popular and critically-acclaimed series of the last two generations. Brawl sold over 12 million copies; Melee is still being played in competitive tournaments 13 years after release. The comparison to Tearaway is even more confusing. That game has yet to sell 500,000 copies. Smash Bros. for 3DS, out for less than a month, has already crossed 1 million.
Now, will Smash Bros. trigger an explosion in WiiU sales? Probably not. Together with some bundles, promotions, and the holiday shopping season, it should push the system to a healthy fourth quarter, though. That said, WiiU will probably come back down to Earth in early 2015.
