As Microsoft moves towards Release To Manufacturing (RTM) We will be seeing more Vista builds being released to not only to msdn/technet, we will also be seeing them being released to Technial Beta Testers and Technology Adoption Program Members. Microsoft is still scheduled to finish the product in October and deliver [Windows Vista Business Editions] it to Volume License Subscribers in Early to Mid November.
However, The General Public will not be seeing anymore builds from Microsoft until its final release In January 2007. Microsoft is scheduled to release new builds to Tech Beta Testers, Technology Adoption Program members and Technet/MSDN subscibers throughout the next few months, these builds are now "RTM" Builds as Microsoft has Delivered RC1 it has now "Forked" the development to start working on RTM Builds, so anything we see or hear about will be from the RTM Branch of Development.
