It sounds like the new PowerBooks may ship with 10.2.7, too. I read on Think Secret and apparently there's a lot changed/updated/added to 10.2.7 such as USB 2.0 support, improved OpenGL, improved Firewire, some fixes to Finder, improvements to Safari, etc...so it sounds like if Panther takes too long to come out, 10.2.7 could be a good update for current Jaguar owners.
