Well if anyone cares, apparently the game was shown off at
another event (at least they're marketing the hell out of the game this time, I don't recall them ever trying to get as much publicity for Tempest and Innocence, they've been at like four or five events and have done a bit of marketing besides those too), and there was some new stuff revealed according to someone on 2ch.
-The number of support characters that will be in the game is in the two digits (I'm going to guess this means somewhere between 20-40 people).
-Shing, Kohak, Innes, and Beryl all had their Hi Ougis (Mystic Artes) shown. Shing's is Shououjineizan, Kohak's is Satsugekibukouken (Final Fury), Innes' is Neptune Rage, and I don't know if it's confirmed, but it seems Beryl's is Crazy Comet finally returning since Tales of Destiny 2.
-It seems they also showed off the Wii Tales.
Unfortunately no one really had anything to say besides that it's 3D and the feel (look) felt like Vesperia's, so it's either cel-shaded (same engine?) or continues the cartoony look of the series.
At this rate I'm wondering if we'll even have to wait for the preorder DVD or Jump Festa to see the game and Jump just won't reveal the game before all that (just with no actual video until the trailer).
