Apparently, it was a mistake - it came from their German office and was a result of them trying to curb the debug version of Dark Souls that was leaked.
Of course it was a mistake, but that never stops people jumping the gun and claiming Namco are a bunch of scumbags who can't do their jobs properly and they won't buy their games any more. Sad really.
Well, with the way this community has been trending are you honestly surprised?
Oh look, it's officially a mistake. Who would have thought?
