Theory: What's taking Busters so long

The Yo-kai Watch U is what's keeping Busters/Blasters from us. Unless they want to just pretend B Medals outright don't exist (which, knowing Hasbro, wouldn't surprise me,) we can't get them until we get the U Prototype watch, since that's the oldest watch that can read them.

Unless, like I said, they pretend these medals don't exist. I have no idea what B Medals do for the game to begin with, but their existence alone makes me think they're at least one major obstacle.
