World of Warcraft's Blizzard has confirmed that 'Titan' is the studio's "next gen MMO" and that's only because they want to "leverage" it as a recruiting tool.
A leaked document supposedly reveals Titan is due in late 2013, however Blizzard would only confirm that 'Titan' is their next MMO project. Diablo III is next.

A Titan Wiki has already been created - while empty for now, check it in the future for all kinds of info about this project.
