Ranting & Raving!
Unless they're lying about being satisfied with the number of Let's Go sales or they don't think Pokemon GO is going to last any longer, I don't see why they wouldn't continue it. Now that the framework for the Let's Go games have been made it would actually be pretty easy and maybe even cheaper to remake the Gold & Silver games in the Let's Go style.I doubt there'll be more Let's Go titles.
The interest for a sequel on gen 2 (or more) would demand significantly more tham just a hd remake of the exact same game.
Plus with all the content they left out (not to mention LG:PE only lets you transfer the Gen I Pokemon from GO), they actually have things to add back in. In a twisted way it's sort of emulating the original experience but with some newer content added in to also change it. So don't expect Abilities until Let's Go Hoenn, but do expect Z-Moves in Let's Go Johto!
But all of this is probably not even in development stage yet. Right now the focus is mainly on the next gen core games and core remakes...
I wouldn't be surprised if they used Let's Go for all their remakes. People have been craving for gen 4 remakes for a long time, maybe that could be next in 2020/21, leaving the next main series game after this year to 2021/22. By then it'll have been long enough since gen 5 for a Let's Go Black/White in 2022/23.
