According to this article, Pikmin 3 will be shown at E3 of 2012, along with a new Mario game, for the Wii U.
If this is the case we can expect to see Pikmin 3 out by the end of this year!
for this info.
As for the contest, which was supposed to end back in February, no one even did it, so It's being called off, sorry about that.
Thank you very much!TheSneakySpy
