They assumed it would pass Vita sooner because they assumed the games would come out sooner. The games have now started to come (Pikmin) and with basically two worthwhile games per month thru December (most of which are first party) I believe Wii U will pass the Vita sometime in December shortly after the release of Super Mario 3D World (supported by DKC: TF, LOZ: WW HD, Wii Fit U, Wii Party U, M&S Olympics, Sonic Lost World, etc.) Don't underestimate Nintendo systems during the holidays...especially when there are many new first-party games releasing around that time.
If you want to discuss something really "funny"...how about we discuss whether the 3DS will sell more in October thru December than Vita has in its lifetime? Seriously, I think its possible with Pokemon and Zelda coming out October and November. Not a Vita-hater...just a Nintendo-supporter, which is unfortunately rare on these forums.
