WWDC 2006: August 7-11!
Apparently, Apple's changing things. It looks like WWDC is shifted from June to August this year, which could have consequences...
1.) So far, we expected that Apple would show developers Leopard (Mac OS X 10.5) for the first time in June, then Apple would extensively test and further develop it until the very end of the year, having it ready for MWSF 2007 at the very, very latest. Now that seems kinda unclear. Will developer testing of Leopard start earlier? Or is Leopard postponed?
2.) August looks like a good time for introducing the PowerMac's intel replacement, since it's about when intel will release the Merom and Conroe processors, both of which are developments with roots in Yonah. The "Mac Pro" is expected not to be available before Conroe. WWDC would look like a good place to finalise the transition, too.
