Game Boy games added to Nintendo Switch Online, Game Boy Advance titles restricted to Expansion Pass - Pokémon TCG GB to be added in future update
At this stage, we have no further information on what other Pokémon titles may make the jump, though with Pokémon Stadium 1 and 2 already confirmed as coming to Nintendo Switch Online, we suspect that the first two generations of Pokémon main series titles could receive releases at some point. If so, these titles should presumably support online connectivity, including trade features, if only to allow players to readily complete their Pokédex. Depending on how the connectivity for these games is implemented, there could also be a chance that these will allow players to export Pokémon to Pokémon HOME, much as the Generation I Virtual Console titles on Nintendo 3DS allowed export to Pokémon Bank.
Unfortunately for fans who might be hoping for this service to bring translated releases of previously Japan exclusive Pokémon titles like Pokémon Card GB2: Here Comes Team GR!, the Japanese version of the Direct showed off several Japanese exclusive Game Boy and Game Boy Advance titles which were not included in the international presentation. Given the precedent of various Japan-only titles coming to the Japanese Nintendo Switch Online apps without releasing on the international apps, it seems unlikely that we'll receive translations of these games. Even without translations though, players worldwide would still be able to access these games by creating a Japanese account on their Switch to download the Japanese Nintendo Switch Online app, and then logging into it using their account subscribed to Nintendo Switch online.
Plan on doing what? You think they won't put the main series games on NSO at all? I doubt it, they put them on VC on the 3DS, I don't see why they can't put them on NSO. This year would also be a great time for them if the theory about SV DLC is correct, then they won't have to compete with a new game.
It's going to be the Pokemon Day announcement alongside the DLC.
