From what I understand, Patty Fleur is the return of the Pirate class in the main game, packing a Gun and a Knife as a weapon and sub-weapon. Her back story is that she's looking for the Treasure of Aifread the Pirate. Seeing as we meet a girl somewhat like this in Torim Harbor, I wouldn't be surprised if she's from there.
As a side note: there a rumor circulating that because of this release, the European 360 version has been canceled, but Europe will be getting the PS3 version first. The source is Namco's Tales of forums, but given what today is, I'd take it with a grain of salt.
Also confirmed is the ToV movie, as mentioned, which is about Yuri and Flynn's time in the Royal Knights.
Tales of Graces looks really nice. I wouldn't mind seeing that one brought over since I felt Symphonia 2 was... underwhelming.
Tales of Vs. would be a fantastic U.S. release, but I don't know if they'll actually do it. It'd be a nice partner to Dissidia as a fighting game on the PSP.
