Let's stop being childish and instead of telling Ubisoft "I'm boycotting the game now", let's rather encourage them by saying "I'm buying your game on Day 1 if you release it now".
Sounds way more positive that way, right? If even the developers want that, then there's no way we should put THEIR jobs on the line when it's not their own fault.
I'm behind those guys! I'm buying it on Wii U regardless, but I'll be even more intent on doing so if the higher heads at Ubi would let them released what's basically a finished product rotting on the side of the road right now. If the developer themselves say "release it now", then it can only mean they're not intending to even work the Wii U version even further, it can only mean the product is good to go and won't be touched upon for the next 7 months.
Moi je vous soutiens jusqu'au bout les gars !! Je veux Rayman MAINTENANT !!
