Around January 2003, Square registered the names Chrono Break and Unlimited SaGa. Then they made Unlimited SaGa but did nothing with Chrono Break, and the registration was allowed to expire a while ago, making it apparent that Square won't be doing another Chrono game for a while. Which is silly, really, since now that they've combined with Enix, they could much more easily reassemble the Dream Team that produced Chrono Trigger.
