Firstly, they can't even spell. Legend of Zelda: Orarina of Time? Secondly, I doubt Kid Icarus: Uprising would be out the same date as OOT, not to mention being merely 5-6 weeks until release, it's unlikely as they would have announced a release date that close, ages ago.
Also, why would it come out in December? It was made to celebrate 20 years of Sonic and is going to come out on the anniversary of the first game. Releasing it half a year later would ruin the entire point.
