I don't understand why anyone would switch from JJP to TBL. Even if Smaug wasn't quite what you expected, they still have arguably the best game programmer in pinball making the game rules. What does DP have? BOP 2.0 never came out, so who knows what you're getting, but the odds are not really in DP's favor.
As a piece of modern art, sure TBL looks good, but right now it's basically a cab and a playfield.
