While talking about the latest PixelJunk release, he was asked whether the PixelJunk series was the main focus of Q Games.
“It’s not the main focus it’s one part of Q…We work directly with Nintendo on second party titles,” he told Siliconera.
“We are working on a Nintendo DS title. Hopefully it will be announced soon, but we don’t know yet. It should finish up soon, but we don’t know when it will come out,” he continued.
We’re as surprised as you are. We’ll provide more information when we dig up some details about the mystery game.
