Apart from Aipom (TWS), three more products are in development codenamed as follows: Arceus, Ariados and Ampharos.
Since Arceus is the creator of pokemon world, we can expect Arceus codenamed product is a smartphone as a smartphone enables an entire ecosystem to work while staying at the center.
Ariados is probably a smart speaker, I am assuming. No idea about Ampharos 🙁
