Pokemon sword and shield no 9th gen?

I would like to know why ninth generation doesn't do switch for you? Instead of a remake of the old games produced

i don't like to have remakes…

Because it takes much longer to think up and design a new generation and region than to re-create an old one. Remakes are a bridge to fill the time up to the next generation and of course to make more money.

What do you think what comes out after platinum remake?

It is not yet clear whether it will be a 4th generation remake. That will probably only be announced in February. I really don't know what comes next.
