I reckon E3 will be the indication of how this generation will kick off. The Wii U hasn't kicked off the next generation with any manner of means....it's been a slow start for them. On thing that is for sure, is that 3rd party developers WILL make games for the Wii U in the short term, but when these studios are dedicating more and more time on PS360 versions and PS4/720 versions, will they have the man power and want to dedicate a team to a version for the Wii U? I doubt it. What we will see is a gradual decline of PS360 versions over the next 18 months with most time being dedicated to the proper Next Gen systems (PS4/720).
I have this horrible feeling that the Wii U will be a 2 year system and die a death once the proper next generation starts to pick up at the end of next year.
What Nintendo NEED to do is showcase a fantastic lineup of 1st party games at E3 along with a healthy selection of 3rd party titles to continue the interest through to the end of this year....but these titles need to come out this year before the Next Gen hit the shelves in November.
