hmmm...thats quite interesting. why would a huge corp like microsoft use such a relatively unused software? must be something to it that nobody's realizing....
trust me, ut2007 will decide the fate of physx. i have one, and i love it. you've seen all the trailers and stuff, so you know what it can do. physics are the future, my friends.
i picked up my physx and yeah, its pretty pricey. cell factor is beautiful, and i'm expecting a lot from UT2007. i think there may not be many killer apps right now, but i think as time goes on there'll be more.
