Microsoft’s recently completed Office Professional Plus 2013 suite is now available for download to TechNet and MSDN subscribers. SharePoint Server 2013, Exchange Server 2013, Lync Server 2013 are also available.
I suspect the availability varies somewhat by subscription type, but with my TechNet Standard subscription, I see Office Professional Plus 2013 (in separate x86 and x64 downloads), SharePoint Server 2013, Exchange Server 2013, and Lync Server 2013. I get two product keys for the client suite and one for the servers. The client download is 667-769 MB.
On MSDN, I see the same offerings, plus Visio Professional 2013 and Project Professional 2013.
I’ll be reviewing Office 2013 in November.
