I'm happy to report that, being DAZ (that is, a highly customer service and rapid response type company), they are now offering a discount and incentive to PRO owners.

Also, they have posted videos within the DAZ forums. I'm sure some of them will make their way on to the product page soon.

I too was hoping for some mention of improved algorithims, etc., but Josh Darling (who worked on the project) said a lot is not included in the manual or on the product spec page. I'll have to ask him if there was an optimization of the code.
