While preparing for an upcoming VMware Horizon View 5.2 to VMware Horizon View 6.0.2 upgrade, I noticed a VMware Horizon View 6.1 column in the VMware Product Interoperability Matrixes. The 6.1 version number also appears on the Version pull-down menu.
Perhaps the next version of View will be VMware Horizon View 6.1. I sure hope, however, that it will be interoperabile with at least one version of VMware ESXi. Maybe View 6.1 will run only on the soon-to-be-released VMware ESXi 6.0.
