Nintendo's playing the only card they have left: nostalgia. MS and Sony can't offer two decades worth of games. I've used emulators before, and nothing compares to being in front of a TV on a couch with friends.

I'm sure the pricing structure (if there is one--remember that Nintendo has nothing to lose by making it free; they've already made money off their old games) will be simple. My biggest question is whether games developed by 3rd parties will be available. Don't get me wrong, I've been itching to play some Mario Kart 64 on a decent controller for awhile now, but I'd LOVE to play a full season of Baseball Stars without worrying about the cart's battery crapping out 70 games in.
