I went for Carrara5 Standard too. It has plenty of new tools that will keep me busy learning for some time to come. I'm getting into animation and video work more and more, so I figure to upgrade to C5 Pro pretty soon. I still find Bryce useful though. Carrara terrains can't be animated, unless you convert them to mesh, so I use Bryce to make animated displacement maps(AVI) to simulate running streams, mudflows/landslides, and lava in Carrara. There are still some things that are easier to do in Bryce than in Carrara. I figure I'll buy the new ver. of Bryce to help continued development.
