Pokémon fans will also be able to play classic games Gold and Silver on the 3DS Virtual Console when they are released on 22 September alongside Pokkén.

The Pokémon stream was also as interesting for what wasn't announced. Many fans were expecting the unveiling of the rumoured Pokémon Stars, which is supposedly a version of Sun and Moon made for Switch. With the Switch's portability, you would expect a dedicated Pokémon game is in the works. But it looks like we will have to wait a little longer to catch a first glimpse of it.
