SharePoint 2016 Beta 2 will be released before the end of November, and should be out before US Thanksgiving (November 26). It will be 99 percent feature complete, so we should get a better view of what SharePoint 2016 RTM will actually look like. Once it has been released expect to see an overview and demo from me once again.
Jeff Teper Corporate Vice President also said that Microsoft is fully dedicated to SharePoint Server, and that SharePoint Server 2016 will not be the last version of SharePoint Server. Microsoft will continue to invest in on-premises SharePoint and hybrid scenarios to bring the power of the cloud to you, even if you run on premises.
