There are two points for discussion here, the capability of a single title to sell a system and having a system reaching a critical mass of must-have exclusives.
For the former point Mario Kart and SSB are unsurpassed, for the latter I think that threshold could be breached, for a lot of potential buyers, next year with the 'smaller' releases.
The WiiU can't win but played correctly it could become a desirable second console. Its standing in this regard is only going to improve with time and weight of releases.
