Although, with that lineup I do doubt Mario wil hit launch, remember, Miyamoto didnt specifically say it would NOT be a launch title. He just said he didnt want to promise something he wasnt sure was going to happen, but then said it /would/ be available within 6 months of launch. So, it /could/ make launch, but given the "gauranteed" lineup we have so far, I kinda doubt it will be. Need to space a few games out, you know? Make sure they have a couple for that infamous dry spell after Xmas?
His exact quote(as shown from IGN)
"[Galaxy] is progressing along quite well, but it's often said that when I get involved in a project I upend the tea table. I don't want to promise anything yet. But if it's not a launch title it will definitely be there within the first six months," Miyamoto said.
So as the saying goes, Cross your fingers, but dont hold your breath.
