Let me take this opportunity to reassure you there is absolutely no change in the RenderMan business and that we remain a separate group within Pixar/Disney totally committed to the commercial CG market and the Renderman product family.
In other news the iTunes music store now has a Disney section with short films, a Disney TV channel, music and audiobooks. So far only the music and audiobooks are available in the UK. But the "Pixar" link has changed to "Short Films" on the UK homepage.
