If anyone was expecting it to support Wii U games, I don't know what they were thinking. You can't just fit an optical disc into a gamecard slot. As for 3DS, I'm not sure if the gamecards are physically compatible either. They could be, but there's always a chance that they're not. I'm kind of expecting them to introduce compatibility with a potential future handheld at some point though (but probably not with 3DS due to the whole dual screen and touching issue).
