Amazon has published new information that reveals Mac OS X 10.4, Tiger, won't now ship until June 30, 2005.

The company is offering Apple's forthcoming OS as a pre-order product at $129, the same as Mac OS X 10.3's US price.

Amazon last week published information stating the OS would ship on March 31, 2005.

Apple has previously said it will ship Tiger "in the first half of 2005".
