According to a retail listing on Play-Asia yes! No details were announced for the PixelJunk 3in1 Pack, but it’s easy to imagine this release, if real, is PixelJunk Racers, Monsters, and Eden on a Blu-ray disc.
Sony used a similar strategy with their downloadble PSP games in Europe by releasing PlayStation Network Power Packs. We didn’t get those so we might not get the PixelJunk 3in1 Pack in North America either. That’s not really a problem since the games are available on the PlayStation Store and if you must have a Q Games collection on physical media the PlayStation 3 is region free.
