TL;DR: My prediction = S3 airs around May/Summer 2014.

Season 2 took over two years to fully complete, assuming they started in March when they were greenlit for a second season (IIRC they finished season 1 before it started airing, and Bocquelet tweeted in April that they had just finished season 2 fully). That could mean season 3 won't be completely finished with production until 2015! D: But that was probably hopefully because they were changing character designs a bit, so now that they're used to them, they'll be able to draw the episodes faster? Oh and the whole internet campaign stuff might've eaten up some time, too.

Also, assuming season 3 follows season 2 completely (s2 took 2 years, 1 month to finish production; episodes begain airing 1 year 5 months into production), season 3 would begin airing in August/September 2014. But again, factors to consider: new designs for season 2 might've slowed down production as the drawers got used to them, and ElmoreStream/Flickr occupying the artist's time. So hopefully season 3 starts airing around May 2014.

But those are just guesses. And pretty grim guesses at that.
