Although we've yet to hear back from Sony Europe, Sony America let us know that it has no "official announcements at this time about the PixelJunk series." If the region didn't deserve a hard copy for Siren: Blood Curse's 9 gigglebytes, what chance does PixelJunk have? Ending on a good note: at least PS3 games aren't region locked.
[Update: Q Games president Dylan Cuthbert confirmed to Joystiq that this PixelJunk pack is Asia-only. "Right now, this special bundle is for Asia only."]
