Wii U is riding the MK8 wave now, it won't last long. Sure it will have two other periods of improvement in sales with SSB and The Legend Of Zelda U, but it will slide down from there on.
X1 just had the Kinectless SKU released so that gave it a boost. Of course its just the beginning of big boosts for the X1, but you can't compare it with Sony doing nothing in the meanwhile for the PS4.
PS4 on the other hand has had reason for potential buyers to wait. TLOU bundle will release in July, and Destiny bundle with white PS4 is also yet to be released. Also they haven't released even one of their biggest franchises yet on the PS4. In Japan it will start selling once the big guns are out, and all of them have yet to release.
