I'm going to correct you before this spins out of control. It'll have a story mode, so please correct your error:

“There will be a single player [campaign], but it won’t be like the [Subspace Emissary] mode in Brawl. One thing we can do with the Smash Bros. series that’s unique to us — because we have all these different disparate characters brought together — is we can create that sort of fan-movie experience as a special gift. But now those things are posted on the internet, it doesn’t really become a gift for people who played the game.”
“What we decided this time around, we’re just going to have [those movies unlocked] from the beginning. We’re going to have a movie for Wii Fit Trainer, The Villager and Mega Man and they’ll be viewable right at the beginning, you can watch those right away.”
