Well, the new Tales game for the Nintendo DS, now dubbed as Tales of Tempest, has had some info shed onto it regarding the raw storyline and main character, known as Caius. A side character has also been confirmed, a childhood friend of Caius, with the name Rubian. It has also been confirmed that the battle mode will remain linear, however all actions will be engaged via the stylus. More detail can be found at these two links:

I personally am pretty excited for this game, though I am kind of anxious as to how the stylus control will work out. =/
