It looks like Microsoft has delayed the release of their release candidate and RTM builds by a month. Replacing the original release candidate build is something they call a “release candidate escrow build.” We have no idea what that means. If you know, please let us know. The actual release candidate build has now been delayed till March. The RTM build of Service Pack 2, which was originally scheduled for April, has been delayed until sometime in Q2, 2009. That means a launch in either May or June, barring any further delays, reports Tech ARP.
