I say XOne.
Not only will Titanfall make a bigger impact than MK8 or SSB, it'll sustain it's boost much longer than the Wii U will with either of its exclusives.
Bayonetta will sink without a trace, it was a niche title on 360/PS3, on Wii U it has no chance.
I also believe MS will show much more at E3 and have more coming out this year than Nintendo could ever hope to have.
Wii U will have zero 3rd party support, aside from the odd exclusive such as Sonic Boom.
