Since I didn't cover it before (my apologies, just kinda out of it lately), Estelle from Tales of Vesperia is returning in Project X Zone 2, this time as a solo unit, while Zagi (also from ToV) is also in as an antagonist. The second trailer for the game includes both of them. A couple of screenshots and voice samples for Estelle and Zagi are also on the official site. The last time I covered this game was before the delay, so know that it's releasing in the west in February rather than this fall as originally reported.
The trailer for the upcoming blu-ray of Tales of Festival 2015 has been put up on the official site along with the boxart of each edition (limited edition that includes both days, or each separate day).
GameSpot put up a video of Tales of Zestiria's opening, and unfortunately it looks like they went with an instrumental version of White Light for the localized release (think of how Tales of the Abyss handled it with a guitar replacing the vocals).
