Nah, I think Stonecutter is just getting a little carried away. Young people do that sometimes.
I wonder if there will be a Space World. I've read somewhere that there will be, but that's not a confirmation. In my opinion, Nintendo should just put all the big guns at E3 instead of spreading stuff out over two shows (because of they're going to have a Space World, you know that Nintendo has to be saving something). But then again, perhaps it is better to spread the hype out over the year instead of just having one big bang in May.
Correct me if I'm wrong, but didn't Mario fail to show at E3 two years ago? Nintendo was sticking with Wave Race and Rogue Squadron, as I recall. Mario Sunshine didn't show until Spaceworld 2001 (where he was quickly overshadowed by Zelda, but never mind that).
