Great news from Microsoft last week. They announced the Released to Manufacturing (RTM) of the wave 15 products, which are:
- Exchange 2013
- Lync 2013
- SharePoint 2013
- Office 2013
The RTM bits should be available on TechNet/MSDN/Volume Licensing from mid-november. General availability is planned for the first quarter of 2013.
For co-existence with Exchange 2010 or 2007, updates for both 2010/2007 is required. There is currently no date for the release of these updates.
Dave Stork has made a great blog post on Exchange 2013 and the different scenarios: http://blogs.dirteam.com/blogs/davestork/archive/2012/10/14/exchange-2013-is-rtm-so-what-now-or-migrating-to-exchange-2013.aspx
