reports that Microsoft has shipped Milestone 1 of Windows 7 to "key partners."
One of the features mentioned is the ability for this version of Windows to support a "heterogeneous graphics system consisting of multiple graphics cards from different vendors.
" I believe that means the OS will have the ability to natively use multiple graphics cards to render the display, even if the graphics cards are not the same make and model. Not 100% sure though.
Also mentioned is that the OS is targeted for release in the second half of 2009, though Microsoft wouldn't comment on that. I know Microsoft CEO Steve Ballmer has said the time gap that occured between Windows XP's release and the release of Windows Vista would never happen again but I'll believe it when it actually happens.
