One of the things I didn't really think was that amazing from Nintendo's conference was the online part. I don't think online is 100% needed for every game, but their online announcements weren't really that great, to me at least. Reggie said that people say they Nintendo is behind for online play, but then he talks about some DS games on Wi-Fi and a handful of Wii games that can be played online as trying to make up for that. It didn't really come off to me as such, just a couple of games having online play, but that's really it.
So has it been debunked or possible for SSBB to have online play? I don't remember and have no idea.
