Asked whether Game Freak was looking at allowing Pokemon to move between Let's Go and the next core entry, Pokemon director Junichi Masuda assures that the development team is working to make that possible.
"We're definitely always thinking of that kind of forward-moving functionality, especially since we've introduced Pokemon Bank," Masuda told GameSpot through an interpreter. "Now, up to Ultra Sun and Ultra Moon, you're able to store your Pokemon, and we know they're very important to everyone. I mean, obviously, people would be very sad if they couldn't use their Pokemon in a future game. So, it does get complicated when you talk about the details and we're still figuring it out, but we do have plans to find ways to let players use their Pokemon in the next game."
