Looks like Christmas came early with the notice that these three products RTM'd (Release To Manufacture). That doesn't mean that they're available for download quite YET, but it does mean that you CAN start building much firmer plans this year as opposed to next year.
TechNet, MSDN and Volume licensing customers can expect to see downloads appearing in the next few weeks – August 6'th.
