A launch date has been announced for Windows 2008 … Feb 27th 2008. That’s probably going to be the public launch date. My understanding is that the RTM is the end of this year meaning that it’ll be available to license program customers (Select, EA, TechNet and MSDN) within a few weeks of being released to manufacturing.
SQL 2008 and Visual Studio 2008 are also scheduled to be launched on this date.
