Panther No Longer Pre-Release?

There have been reports that Apple has seeded new internal releases of Mac OS X Panther (7B80 and 7B81).

While there's been a significant amount of attention on the updated Apple Logo found in Mac OS X 7B74, according to an anonymous report, build 7B80 has another subtle but notable change:

This correlates with reports that Apple is putting the finishing touches on Panther. Speculation has placed Panther's final release in October, with one Page 2 Rumor hinting at a October 24th as a possibility.
