As long as X and Bayonetta 2 are going to be released in 2014, the year will be great (at least I will be satisfied).
DK, MK8 and SSB are 100% sure. SMT x FE and Yarn Yoshi are improbable. I don't care about Hyrule Warriors.
I think they'll anounce something before March 31 to satisfy investors and E3 will be big.
There could be some more Japanese 3rd party exclusives.
Not sure about multiplats from Ubisoft, Activision and Warner, but they wouldn't change Wii U sales... I bought them on Wii U in 2013 to show some support, maybe I'll have to switch back to PC in 2014...
