They now have a "Pick a Model" program, where they display two models on display and fill about half of the PaB bins will the parts for those two models. The models will cost $4.99 each and the store employee explained to me that customers will not be allowed to include the "Pick a Model" parts in regular PaB cups.
The models weren't awesome, and the parts used in them weren't all that exciting either. If memory serves, they were a giraffe and an prop plane.

I didn't do a piece count on either model, but just eyeballing them they looked to be at or above the golden ratio.
Obviously, this is bad news because it really limits the number of different pieces on the wall. But, as the Brick Specialist pointed out to me, there really isn't any way for store staff to police the wall, especially on a weekend or during any other busy time and he expected the "Pick a Model" pieces would end up in regular cups.
Also, according to the Brick Specialist pointed out to me, The "Pick a Model Experience" had been piloted at several stores last year and it was well received. See . Strangely, there's been very little discussion of the change on the LEGO oriented web. Just and from what I could see.
