In it’s E3 today, Nintendo revealed more about the upcomming Let’s Go, Pokemon! titles. They confirmed that Pokemon can be transferred between Go and the Switch-exclusive title, and that Pokemon will be able to follow you on map, regardless of who they are.
The Pokeball peripheral was revealed to be the ‘Pokemon Plus’, which allows users to ‘take the Pokemon with you as you go’. Each Pokemon Plus comes with one free Mew inside.
The title is expected to release later this year, November 16th.
