A lot of the stuff for 10.2 will probably be on their website for years to come. You can still update 9.x through the System Update utility, and there are all sorts of 7/8 era downloads on their site still.

Anyway, great job on the 10.2 disk. It's useful when you have older Macs that can run it, and really, the stuff on disk 2 is X11, ancient itunes and extra languages.
