Yes, but these aren't iApps. Even to get good results with photoshop, you have to know what you're doing - and that's only 2D. And as someone who does 3D everyday - photoshop is just a tool for my 3D - creating texture maps and such.
Its one thing to do video and photos - Poser would be a much better choice, yet that is limited, Bryce is not that great for modelling, and Strata - well, they've been having a tough time. They offer a free base package and you pay for extras, but it lacks a lot of the tools and options that would make it a player in the professional 3D market.
I still say if it happens, EI will be the one bought up - that and FormZ used to be the premiere 3D animation and modelling packages for the Mac for the longest time.
