Pixologic guys stated that these are just a "sneak peek" of some of the features in the next release of 4R7. So I await in much excitement of what will come.
It's late here... I waited for another Pixology demo... and it's the same stuff... (at least for now). I'm going to bed. I want some sculpting awesomness :<
Reviewing the work and process of other artists has a long and meaningful historical value to the art community. I'm glad to see Pixologic putting that up front. Some great artists on display there.
