Apple's yearly developer conference should see iOS 8, OS X 10.10, and likely some hardware.
Mac OS X 10.6.7 Adds Support for New AMD Graphics Cards
As reported by tonymacx86, Apple's new Mac OS X 10.6.7 update for the 2011 MacBook Pro includes support for a number of AMD graphics cards not currently found in Apple's machines. While the development is certainly of interest to Hackintosh fans looking to build their own systems running Mac OS X, the inclusion of the new cards may provide some hints of graphics cards to be included in future Macs such as potential iMac and Mac Pro updates.
The following graphics cards appear to be natively supported:
