Craig, I should add that there are different ways to look at this. If you are a home user making pretty pictures for your own amusement, then the current "classic" version of LucisArt is fine, and will hold you for some time, with the following exceptions:
You will get no further technical support after the upcoming deadline, and if you are a Mac user, you will need to stick with pre-Intel hardware (or run Photoshop under Rosetta, which kind of defeats the purpose of getting an Intel Mac and CS3). Plus be limited to 8-bit processing, a small preview window,
comical interface on the Windows version, etc.
On the other hand,
LucisArt Pro offers 16-bit processing, a simple but highly flexible two-slider interface, access to separate RGB channels for individual processing, etc. I'm currently testing a pre-release version and find it incredibly easy to quickly slide from effects of one extreme to the other (ie, there is no single "Lucis" look, though the "Dave Hill" effect is the most common). Every image will generate different effects depending on its original color and contrast.
I've spoken to the developer personally about the new pricing scheme and she indicates the many working pros she's interviewed (portrait and wedding studios) are eager to get ahold of the new version because of its modern specs (the current version is over four years old). She's also related stories of studios buying LucisArt and immediately greatly increasing print sales, dwarfing their original investment in the software.
So it seems the new price will separate the men from the boys in terms of who can create and deliver these unique effects for clients and who can't.
I'm thinking of a fun challenge as the release date for LucisArt Pro gets closer: Post a few wildly divergent versions of an image treated with Lucis effects, and try to duplicate those effects using Photoshop and/or other third-party software, with special note of the time it takes to create each challenger effect and the complexity of the process involved. If the Lucis effects can't be duplicated, great. If they can but it's much harder and slower, that's telling as well.
