If you're a TechNet subscriber, you can now download the RTM version of Exchange 2013 and Office 2013 Professional Plus, the version that contains the version of Outlook 2013 that exposes all of Exchange 2013's features. Microsoft released the code earlier today.
Of course, there's lots of work to be done to prepare for the deployment of these products and some companies won't even touch the RTM bits as they will consider that waiting for the first service pack to be a much better plan (see "Exchange 2013, Facebook, malfunctioning ActiveSync clients, modern public folders, and more at TEC Barcelona" for some reasons why companies wait). Even so, it's great that the code is now available to allow testing to begin, including the work that third party software vendors need to do to ensure that their products work well with Exchange 2013.
Remember that you need updates for Exchange 2010 and Exchange 2007 to allow these versions to co-exist with Exchange 2013. Microsoft has not released this code yet. Exchange 2010 SP3 is expected in early 2013 and no details are yet available as to what software version is necessary for Exchange 2007. Remember too that you need to update the Active Directory schema to support Exchange 2013.
Lots of work to do. Let's get going!
