That could very well happen in the future, Spork. They've already made animations for Tales of Eternia and Tales of Phantasia. A series for Tales of Symphonia wouldn't be a far fetched idea at all.
Anyhow. I quite liked Tales of Symphonia. It was easily the best game I played last year. Awesome cutscenes, despite a lack thereof, fun battle system, and a pretty good story, though a bit cliche. Very good game, to say the very least.
