Black Ops 4 will win since there's not much hype for RDR2.
Firstly, it's a wild west setting which doesn't appeal to this generation that much, not an interesting place to be. Second, the first game released 7 years ago so safe to say that the mainstream i.e. casuals, kids and the mainstream audience of this gen do not have any resonance with the name at all. And lastly, Blackout has been met with positive acclaim and has been killing it on Twitch and will probably be a Twitch mainstay. Black Ops 4 will be the biggest game in a long time IMO, Blackout is honestly great.
RDR2 also hasn't had any big marketing push at all, there's next to no gameplay and there's no show of any multiplayer which is what most of the mainstream GTA fans would be looking forward to. Honestly, there has been no hype building for this game at all, it has had zero presence in the gaming sphere. There's nothing about this game that will appeal to the kids or even casuals.
Black Ops 4 will win easy.
