RE8 is already in development (and has been in development for around a year and a half now) and there's a couple other RE games in development right now outside of REmake 2 & RE8, so we're not getting a string of remakes in a row and rapid succession or anything. It'll more likely turn out we'll get REmake 2 now, then a few other RE things in the years that follow (I'm placing my bets we'll see see RE8 in 2020 and maybe some other RE thing in 2019), and we won't see REmake 3 until 2021+ or something.
Like, I'm talking about hoping for a Code Veronica remake, but honestly if that were to happen we'd not see it until at least 2024 or something. The current rate of making a RE game is around three years as it stands. Though varying factors in this, such as the actual time will take longer if for example, a version of the game is scrapped in the middle of production. The reason there was kinda' a new RE game lull after RE6 was due to several factors, one of them being that there was a scrapped third-person RE7 concept before the RE7 was know, Revelations 2 was something else before it was scrapped then redone, etc., so RE7 as we know it only took around three years to make for example, but in actuality it took around 4-5 years since a year and a half of that was dedicated to a very different RE7 that was scrapped in development. REmake 2 was never scrapped in development, so that's part of why it's been able to come out so quickly. Likewise, if the current RE8 gets scrapped (which it'll be up for review pretty soon as REmake 2 is coming to a close development wise), if it does get scrapped we probably won't see RE8 until at least 2021, while if it keeps its current iteration we'll probably see it in 2019. Not including spin-offs (I think most people at this point realize REmake 2 is being treated as a mainline title, not a spin-off), typically as soon as one RE game is finished being worked on another is almost immediately started, there's almost always two RE games in production at one time, just one with a larger team, one with a smaller team. Once REmake 2 is done, most of the team will move onto the next project, conjoining with the smaller team (in this case, RE8), while a smaller team will be made to start work on the project after this (in this case, most likely REmake 3 if REmake 2 does well). There also may be smaller teams working on spin-offs/ports/remasters in the background of all of this too.
But as a result, Capcom isn't just focused on making RE remakes right now, if REmake 2 does well we'll see REmake 3, and I think a lot of people want that to happen, but it's not like Capcom is going to stop making new RE games, and though it's fun to talk about these remakes, the truth is they're still years out and we won't even see a REmake 3 for example until at least three years from now or so most likely (I kinda' don't see a scenario of REmake 2 bombing, and think it'll do very well, so I'm fairly certain REmake 3 is going to happen at this point).
