I think Star Wars has more of a chance to be Stern's TAF but I still don't think any Stern will break TAF's record. I still think the resurgence in pinball has a long way to go before it reaches the heights of the early 90s and it will never reach the heights of the late 70s.
Star Wars has a good chance of being their best seller though. They are releasing popular Star Wars movies right now and if it's a good game and releases around the same time as a movie, it could do really well.
If Stern ever had a game break TAF's record, you can rest assured that they would let everyone know.
GB is a big deal for collectors but little appeal to the mainstream.
