Possible Skyward Sword release date? To be released with MP?

Our good friend Ilu, a webmaster of our affiliate Knights Of Hyrule, has posted a (now very famous) picture of Gamestop listing the Skyward Sword release. 1st of April. Is it an April fools joke? Yes, I am aware of this belief, but remember that it’s only a belief because it’s the 1st of April. Who knows? Maybe Gamestop can be trusted on this one? And in addition to this, it may be released with Motion Plus! 
Anyway, great thanks to Ilu for telling me, (Which more sites should credit “cough, cough” I’m pretty sure she took the photo herself!). Sorry I couldn’t post this the day before, I was very busy with the podcast editing. See the original source here.
