Well, it looks like @TravisD 's rumor is correct2nd hand word that I got from someone who is goof friends with the BTS folks is that they're planning to return in 2023... Obviously that's aspirational and subject to the realities of things.

For those of you that don't already know: BTS is a consumer-desired show open to the public. Unlike DEMA, you don't need to be a "pro", LDS, manufacturer, or know somebody.
