Assassins Creed for Wii U?

I've Been doing some serious digging recently into whether ubisoft is making the jump from Sony to Nintendo for Assassins Credd which was confirmed to ahve a unique game coming to the Wii U soon after the launch. But now that the launch of the Wii U has been puched back to September, have Ubisoft pulled the plug on this idea? I think thta as the Wii U is supposed to be the future of gaming that they will try as much as they can to get an Assassins creed game onto the wii U to satisfy fans.

Any way I'll post any more Info I find as soon as it's revieled! :)
