I picked the Wii U version because the last time I looked at the pre-orders charts, the Wii U version had a more than 50,000 pre-orders while the other ones weren't even listed. Also, the Miiverse Rayman Legends board has been favorited more than 60,000 times, more than most Wii U games. I think that's a good indication that a game that has a niche following will probably do well on that console.

What about north america?

That's true. Well, I can't really see the vita version beating out the others at retail. No clue on how many digital sales it will have though.

not delayed as far as i know. Vita and WiiU have the best controls but Vita version will be missing every speed run level. it was confirm like 2 days ago. my guess cuz its handheld and didn't have enough room?

You'd like to think Wii U really. But I'd say PS3 then 360 then Wii U then Vita. All I can say for certain is Vita will be lowest and it'll bomb on everything.

My guess:
PS3 > Wii U > PS Vita > Xbox 360

PS3 > Wii U > Xbox 360 > PS Vita, if we aren't adding the numbers of the first week after release in Europe for the PS Vita

Possibly, however I woudn't be surprised if they just ran out of time. The Vita version was only announced a few months ago.

I'll be picking up both Wii U and Vita versions for an ultimate home and on the go "at work", experience!

Voted PS3.

Even though I expect Wii U to really pick up later thsi year, i don't know how well RL could do against SM3DW and DKCTF. Not to mention NSMBU which I expect to be a hot seller this holiday.
