Wait for YW2 and Pokemon and MH4G. That will be enough to get a decent year.
Though, yes, i think it'll be one of the worst nintendo handheld in sales. It'll be a shock for Nintendo, not really good for them this dying market when their home console is not doing so well. I think they'll have to launch their Fusion console soon ( it's a great idea considering handheld market is dying, so fusionning both market is genius )
Predictions for end of 2014 HW sales:
PS4: 17m XB1: 10m WiiU: 10m Vita: 10m
