This game is an experiment. Game Freak will be eyeing at reviewers.
They have Gen 8 in development, but this "Let's GO" game has quite a few deviations from a main series title.
Like the lack of random encounters, the GO catching mechanics, Pokemon following you in the overworld, etc.
If any of these features are well-received, expect them to be implemented in Gen 8 somehow. Otherwise, we could well expect a "Let's GO" line of games if this is successful. I think we'll probably see:
2019: Gen 8
2020: Sinnoh remake/Let's Go sequel
2021: (Or)
2022: Gen 9.
