Unless they completely revise the structure of the game from previous titles, I don't see how it will take long. While there usually is a LOT of content in Super Smash Bros games, the content itself isn't anything that seems like it would be time-consuming to produce. I'd say 2013/2014 seems likely for a release date, and considering how the console is releasing in 2012: that's not a big deal.
