John Gruber, TUAW has a
rumor about this:
TUAW has received some information that suggests Apple may be working to seed developers with an early build of Mac OS X 10.6 at this year's WWDC. 10.6 will not include any new significant features from 10.5; instead, Apple is focusing solely on "stability and security." We have also learned that OS X 10.6 may go gold master by December 2008 in an effort to start shipping it in January '09 at Macworld Expo. Mac OS X 10.6 will be a milestone release for Apple, as it will leave the PowerPC behind: a fully 64-bit clean, Intel-only Mac OS X.
This is sort of what I was thinking---not the announcement now, or the release date, or the dropping of PPC support---that the next version of OSX wouldn't introduce new features but would focus on cleaning up things and unifying the look and feel on different platforms. Interesting rumor, in any case.
