I don't think they will separate them anytime soon. I believe the next 3/4 cods will all get a remaster with them (WAW/MW2/BO1/MW3) so if they start a precedent of selling the remaster separately people in future will be like nah, not buying the new cod, I'll wait 6 months to get the remaster.
I'll be getting the $120 version which includes the base game, the season pass and cod4. First call of duty I've bought since MW3.
