I hope you don't mind but in addition to using ArtRage I also use Sketchbook Pro. The 2010 version is available as a trial download. You might want to check it out. Plus FINALLY... autodesk has a new web site and seems to be paying attention to it's users.
I LOVE ARTRAGE and am eagerly waiting this upgrade too, and I love this forum, everyone is very helpful and kind, this is why I'm posting this note.
Cheers to you all.
