Let's hope so...
acutally, M$ used to own Softimage, they sold it once the PC was established as a 3D platform. Avid owns it now. I still don't see a mac version there anytime soon. Same goes for Discreet and 3DSmax, unless they rewrite that whole damn thing.
Not sure about the price battles, though. Margins are already pretty thin as it is right now, especially since the massive price drops last year. I think it is going to be more of a feature war now, which is a good thing, too 😀
But things don't look too bad for 3D on the mac in general right now, with Kaydara dropping linux support in favour of OSX, Luxology and Pixar praising the G5/OSX, Maya, Lightwave, Cinema4D, Zbrush...almost too many toys to play with.
