From what I can tell, it looks like Cover is footing the bill for this. (fucking finally) Which should mean a rented out 3D mocap studio. So, it should be more 3rd FES and less kanauru.
Calli should be one of her guests, since she talked about heading back to the states. (unless I got my timeframes mixed up; did Goomba outright confirm this?) I'm on that hopium that Kiara might be there too, but she hasn't said anything about it, and she's pretty bad at keeping secrets.
It's not in Japan, but as long as Gura is getting the same support as JP and now ID girls, this should be a good time.
