That's what has been announced at today's press conference. Apparently your source has updated their site in the meantime. Now they only speak of "rumors".
Bandai Namco has announced new RPGs for both PlayStation 3 and 360 last year. However, the RPG for the 360 was previously mentioned to be an original title, not a new Tales installment (even though Tales Studio staff is apparently involved in its development).
As for the Chrono story, I wonder how many times you can bring up those kind of stories (Chrono Cross X on Xbox and whatnot) before people stop falling for them :P? This stuff is getting old quickly.
