Congratulations and good luck!
Sculptris is something of a second revelation after what Zbrush had done to the industry some years ago. Once there's a natural merge and some of the conventionalities of Sculptris inspire Zbrush, too, to accept a few more of them, it could well become another giant push into a better world for artists.
There is a slight teardrop to the departure of Sculptris and its development from the "free" world, but with the proper respect of the aquiring party, pixologic, and its monumental following, it could certainly reach another level of greatness altogether.
Tomas is one of the most brilliant and promissing guys I've ever met and it gives me great joy to see that someone can support his continuing focus on the subject of 3d sculpting. I sincerely hope he will be given the freedom to let his mind wonder into all his other directions, so his full and fresh capacity can function when it comes back to Zculptris. ;)
