This makes a lot of sense as more and more functionality in the Adobe Creative Suite is moving to 64-bit, using GPU acceleration, etc. In other words, backwards compatibility is getting to a point where it is no longer viable to support the old platforms.

I seem to remember migrating to XP because some newer software was no longer supported on Windows 2000.

Yep, legacy software support is problematic both from a technical and a business point of view. New operating systems offer new features that software developers need to take advantage of to stay competitive (and efficient). There comes a point where older systems simply can't support the feature sets possible in a newer OS.

On top of that there is the business reality that the vast bulk of new software is bought for new systems. While individual owners of legacy systems may wish to by new software the bulk of such owners keep their legacy systems because they can't afford to upgrade or because the systems serves a fixed purpose (running legacy software that is no longer available). In either case these people aren't an active market for new cutting edge software so it simply isn't economically viable to support those systems.
