DAZ says they will treat all Bryce customers the same, whether you bought it from Corel or from them.

But they say there will be no upgrade pricing. They might change their minds about that, because people are upset. Dan Farr said something about maybe giving people who already own Bryce 5 some kind of bonus for upgrading. (Free models, a coupon, something like that, I presume.) Another possibility would be to offer the introductory price only to previous owners.

OTOH, at $99 (less if you're a PC club member, or have that "bundle" coupon), the whole program is cheaper than, say, Vue 5's upgrade price.
