This means that we are very close to getting our hands on Windows 7/Windows Server 2008 R2.
There's also an update on when we will see v2 for XP, Vista and Server 2008. Missing from that list is Server 2003 though. I'm not sure if that was just an error/omission or there's a problem with v2 support for Server 2003.
