Well that's what I was hoping for haha.
Even a game-specific Direct would be nice to get the core Nintendo fanbase on board (who are the ones supporting the Wii U anyways). Any sort of advertising is key at this point. I know they've already begun with in store advertising, which is good to see.
They should make a special amiibo for it that comes free with every pre-order. People who are crazy about amiibo might have more incentive to pick up the game early.
