Ya it seems odd that they still have so many unanswered questions this close to launch, I thought thats what the presentation and subsequent interviews & hands on impressions were for.
I hope they do a pre-launch Nintendo Direct or something that clears alot of this up and shows some of their post-launch titles in more detail with launch dates for Spring titles.
I'm not sure if people realize that as of right now, we don't know if voice chat is going to be possible at launch. How on earth is that acceptable? That information has to be known at the very least. Nintendo has to come out with more information about this console and it has to happen very soon.
