Crystal balling now, but I predict the price point gap between second hand Stern Pro and LE models to become even more pronounced (particularly Pro models falling)

I would wait on this one for a while (unless it is a must have).

Another outcome that Stern didn't anticipate with the tiered pricing model (or maybe they did?)

Like most things it will come down to supply and demand at the time, some of the Stern pro pins that have not had multiple LE versions made might do better than the ones that have had 2 or 3 LE versions and it might come down to individual titles as well and how popular or unpopular they become with old and new buyers alike.I guess time will tell.
