Much as I would love the idea, it probably just isn’t super realistic. Not unless they wanted to throw their hand in the ring with a “handheld gaming PC” to compete with Steam Deck or the ROG thing.
That said, I would absolutely KILL for a “Dreamcast Mini” console. Saturn would also be cool, but realistically that should probably skip that since the demand really isn’t there. But you give us Sonic Adventure 1&2 Dreamcast versions (with all their “dlc” included), and PSO, I would be super down for that.
