How many mainline Pokemon games will Pokemon Legend Arceus outsell?

What I like about this game, and what I think will slow sales down, if only a little, is that there is only 1 version of the game

Past entries had 2, sometimes up to 4 total versions to up the sales and a good handful of people, myself included would by both versions.
I think it will sell between 10 and 15 million lifetime, and that's partly because it just seems a bit underwhelming for a late gen switch game, and I've seen quite a few people say they aren't interested in it

Those figures won’t include games like Yellow, Crystal, Emerald etc, which are listed separately.
