"Iwata summed it the basic idea nicely: players would spend time on the 3DS version, building up their character and collecting stuff, then show off their skills on the Wii U version.
Sakurai noted that as the Wii U is an HD system, this version could offer 60 frames per second visuals, high quality graphics, dynamic effects, and smooth character movements.
While it is important to have both versions of the game be enjoyable on their own, Sakurai feels that connectivity between the two versions will make the experience even more enjoyable.
Closing off the little section offering vague hints about the new Smash Bros. games, Sakurai said that his aim with the 3DS version is to offer players a slightly different experience from conventional Smash Bros. games. He believes that there is merit in having skilled and unskilled players play together, so one emphasis will be on elements of players helping one-another."
