SoMeh doesn't seem to have a track record, and that we've known of the titles of Pokemon: Let's Go Pika/Eev since April 1st (RealLeaks).
I would rather want to believe from the words of someone else with a better track record, than of someone who hasn't posted much of anything on Reddit.
Let's Go is going to sell freight-trucks, especially as it has a lot of things going for it (G1 Pokemon returning, Pikachu/Eevee, Console Pokemon RPG (even if Casual), and should intice also people who were kids when they watched the Generation 1 Anime to see that their favorites are back).
And for newcomers, Let's Go will be the entry-point, as it will have all of the first 149 Pokemon (along with possibly some new ones, and the Alolan Forms).
