If this is true, it's interesting to me...
They make very minimal changes to the playfield between Tron and Tron LE, and after Tron LE sells out, the Pro continues to sell and sell and sell.
I wasn't at all interested in the Pros for anything since Tron because the differences are so dramatic, I'd rather not have the stripped down model. Makes me not pursue them at all, really. With Tron though, the fact it was so similar to the LE made me very interested in it. I wonder if the continuing Pro sales make them think about not making such huge differences between the Pro and LE models.
