Sega Japan teaser site for a new Vita and PS3 game

With Northern Spring almost upon it looks like the developers and marketing types are waking from their winter snooze. This is yet another teaser site opening up with a countdown for a week's time. With its ethereal gauze and lightfall, it reeks of RPG, but could really be anything

Chatter on Japanese sites is for a Valkyria game, but hopefully its for something all new. Personally, with Shining Ark not really doing shining sales on PSP, I wonder if they'll promote that to a full-spec revamp? The Facebook link goes to a new page, but there's nothing to tease us further.
