>I would guess that 10.5 would have substantial support for 64-bit pointers in all the lower levels (libmalloc, libc, etc.) but probably not in Cocoa or Carbon. The full transition will probably take close to 3-5 years.
IMHO it will never make it to Carbon, for two reasons.
First, it would take an extremely tricky hack to make it work with the old OS 9 APIs (particularly since there will be no new versions of OS 9); just remember how hard it was to go from 24-bit to 32-bit memory addresses 10? 13? years ago.
Second, there is at a minimum a strong implication that Cocoa is the wave of the future, and Carbon is a transition from the past. Apple is using Cocoa APIs for its new applications and has even migrated perfectly good apps from Carbon to Cocoa.
So as Brendan said, we'll probably get 64-bit BSD APIs first, Cocoa second, and Carbon about the time that Apple starts shipping OS 9 machines again.
