Okay, wild speculation time. The teaser shows Red, yellow and blue balloons, the GB intro music, and Gen 1 Pokémon. Fine so Gen 1 games comes to switch virtual console, that’s was fairly obvious.
But…what about what we are not seeing? Why not any nods or winks to gen 2 too? Maybe they are holding them back from virtual console release because they are going to announce a let’s go Johto game and don’t want to divert away from the hype of a new game release… or am I dreaming?
