We have just gotten an anonymous tip from a source that indicates that Apple is planning a special event on February 20 to introduce Mac OS X 10.5 (Leopard), iLife ’07 and iWork ’07 as well as updated Mac Pros. Mac Pros will be available immediately with a free upgrade to 10.5 when it ships, and the ship date for 10.5 will be confirmed for 3/24/07 as we have been predicting for quite some time now.
