According to a rough translation, Sakurai says "Wii U and 3DS versions -- I would like to show you both." He then explains that “Other games have had visuals shown, but you still have to wait for Smash Bros. But we'll be able to release something better.” Sakurai apologizes that the production of the game was announced so far in advance but says that there will be more things coming, so fans should be ready.
During Nintendo Direct, Iwata said that “screens” from Smash Bros. will be shown, but Sakurai makes it sound like we may indeed be seeing footage instead. We'll have to wait to find out for sure, but at least we know that more info will be coming soon.
