Xseed Teasing something! Could it be Pandora's Tower?

[Torillian]

Pandora's Tower is pretty great, but I don't think they'd be that obvious with it for a hint, just taking a picture of a tower in the rain.

Personally since I've played PT already I'll hope for Ys IV: Sea of Trees, which is another game I hope Xseed will announce any day now.
