Oh, Symbian, you tease! For an organization as committed to openness and sharing its roadmap (and its code) as the Symbian Foundation, it's pretty unusual that they'd be counting down to a big unveiling of anything -- but sure enough, they've been tweeting decreasing numbers with the hashtag "#symbiancountdown" starting back on January 26 with 108. Today we're down to 12 (it's hard to say what sort of jacked-up counting system they're using here) with a note of "what will tomorrow bring?" so it looks like we can expect this all to go down in just a few short hours. One thought is that they could announce that Symbian^3 has gone Functionally Complete, a key milestone in getting it pushed to devices -- but that's a shot in the dark. Don't disappoint, guys.
Update: Looks like it may be the full source for Symbian^2, the Foundation's first open release.
Update 2: They've gotten around to tossing up a blog post about it, and it's actually Symbian^3 that's going open here, which "will soon be feature complete." Good times.
