Great, there had to be misinformation involved. Steve Purcell says that he worked on the art for the DVD's slipcase
, which doesn't mean that the DVD's cover needs to be different.
Basically, the whole deal was always publicized as whoever preordered would get an exclusive slipcase
with their Collector's DVD.
I really hope Telltale avoids sticking non-preordered versions of the DVD with a bad cover. That would really piss some fans.
