Go previously befriended Suicune in the new original series, and although they are now separated, they are still connected in their hearts. Therefore, Go is in a position to reunite with Suicune whenever he wishes.
Since Go has been traveling around, it is highly likely that he will appear in the anime again in some form. It is also worth noting that Yamashita Daiki is the voice of Roy's Attacker and Pokédex. Yamashita Daiki also voiced Go, so we can expect Go to reappear due to the connection between the voice actors.
