Blog post from Seth Patton, senior director of product management for the SharePoint team.
Today, we are confirming that SharePoint Server 2016 will become generally available in Q2 2016, with a public beta planned for Q4 2015. We also want to confirm our commitment to delivering on-premises releases of SharePoint for the foreseeable future. We envision a future where we will continue to have customers who choose a combination of on-premises, cloud and hybrid deployments for many years to come. We’re excited to start sharing information on our SharePoint investments at Microsoft Ignite, so below I’ve highlighted some of the most relevant sessions to attend if you’re interested in learning more about the road ahead.
