Not only has this peen posted at pinball news but I've heard it from a few people. It seems like Stern's next pin will only have one PF.
From pinball news:
Continuing with his the current game he is designing for Stern, he said it is coming out right after Star Trek, and the Pro playfield design will be the same as the Premium and LE.
I'm only going to assume this will relieve some pressure on the programmers who have to code for two variants all the time.
