Not by much, but a lot of this depends on if there is a price drop to $350 and also whether or not they offer any good bundles.
One of the main reasons I think that the X1 will outstrip the Wii U by the end of the year is thanks to it's 3rd party support. Every time a big 3rd party game comes out, X1 will get a bump in sales (even if not big), and then on top of that, it will get even bigger boost from its exclusive titles like SO, FH2, & Halo MCC.
The Wii U will only get boost for it's 1st party titles comming out (they don't have that much for this year), and also for the holidays.
All in all, I would say it will pass Wii U by between 100k-500k by the end of the year. It won't be by a million though.
