Honestly, I don't see a lot of demand for this game. I doubt anyone plans to buy a PS4 because of this timed exclusive.
It seems to be doing fine on amazon and other sites, the trailers get a lot of views and more anecdotally it's one of the few games I've seen people on facebook talk about that never talks about games.
A lot of people played and loved the original games. So I think it will do fine and I don't really see the concern
