Dylan Cuthbert of PixelJunk-maker Q-Games has "posted a little sneak preview of something we'll be revealing next week at Casual Connect" on Google+. Social media!
His post, which includes the image above, is viewable here. Looks like PixelJunk Something or Other to me. Possibly even a little Facebook-y, especially given that Casual Connect is about "iPhone, Social, Android, Flash, Browser MMO, and Download Games."
Whatever it is, I'm on board. Q-Games hasn't let me down yet.
