Hehe, I thought Playroom was DoubleFine!
I do wonder what London studio is up to.
We know they're making a new engine for PS4. There were also a few rumours knocking about concerning Singstar F2P for PS3 and a job listing appeared a year or so back mentioning an AAA PSMove title for PS3.
They're a big studio so they could easily have 3/4 projects deep in development.
I imagine they'll remain Sony's casual studio for next-gen whilst also still heavily supporting the PS3. That's not to say they won't make a core title as we all know they have had several core projects in dev at one point (e.g. Eight Days, Getaway 3...)
