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?)

Edit:
There is another run of Tron Pro being done as we speak by Stern. Friend in the US just had his delivered yesterday - build date April 19th 2012.
