Nintendo plans to be a presence at the upcoming Tokyo Game Show.
For the first time since the creation of their Shoshinkai/Spaceworld show (as far as I know), Nintendo Company Ltd. will be exhibiting at the Tokyo Games Show. The Magic Box says Nintendo will be there to hawk its Game Boy Advance, and perhaps also to steal some attention with GameCube demos. I'll go one step further and say that it's not out of the question that Nintendo might have playable demos there, if only behind the scenes for media and investors. The Spring TGS will be held on March 30 through April 1, so cross your fingers for some new GC info and maybe some new confirmed GBA games!
