Hello Pixologic, How about sculptris for IPAD. I got a pressure sensitive pen, ok its not a cintiq, but just for fun and practice on the bus is a must!. I feel how about sculptris on my Ipad? The Autodesk softwares for Ipad sucks!!! I´m sure Pixologic will do a big deal put a free software on the market.
Think about that.
I don't work for Pixo, but don't expect it any time soon. Sculptris was left an Alpha (meaning not finished) and has not been updated in 3 years. Dr Petters (the Creator) last posted in 2010 here in the forum. I don't know if it's possible (graphics cards and such) but I would look for Wings3D or Blender to come out with a pad or phone version eventually.
