Without a doubt, the Black Ops series from Treyarch has been a constant success with black ops 3 being the most successful out of the jetpack era. I have hope they can pull off an awesome and epic boots on the ground game that WW2 failed to deliver. I'm sure they will add in their loot box garbage but that's a given with COD now.
Treyarch never fails to satisfy fans with their COD games, all of them have been really successful so here's to hoping they can pull off a massive win with Black Ops 4. Let's hope the killstreaks are awesome, map design is sexy, heaps of guns and cosmetics and it actually works on launch. Basically, make it the opposite of what WW2 was and the fans will love it.
