let me elaborate a bit on what i mean, something i was thinking about yesterday. 
Planescape was designed using just about everything that was ever written about the planes (as much as it was feasable to do so), then adding it all together and amping it up to the nth degree. for the most part, if it was something that existed before the PSCS came out, you could still use it in planescape. this, i'm sure, was intentional.
the designers of 3E decided to change a great deal of how the way things worked in some fundamental ways - something that had never really been done in D&D before (which was probably part of their argument for why such changes were necessary). these changes ripped apart the fabric of what made planescape work the way it did.
i suppose PS could work in this here new millenium if some brave souls went and redesigned it *FROM SCRATCH*. trying to retrofit it will just make it ugly. a whole lot of things will disappear from it, and a whole lot of new things will appear in it - it will not be as smooth of a transition as some settings have gone through. it will be like giving birth to the same baby twice. ouch.
