First, you are mixing OEM programs, old&new product names. VxRail, VPEX Blue, VSAN and EVO:RAIL are just a way of saying "appliance based on VSAN" are are essentially the same entity. If you remove duplicates you will see three distinct categories: "blocks", "racks", "appliances"
Second, you are mixing solutions from two different vendors: EMC and VMWare. These are two separate companies.
Third, Gartner is on Earth and they believe that there are three different categories under Integrated Systems. Hyper-converged is just one of them. See the first page of their Magic Quadrant: http://www.emc.com/collateral/analyst-reports/magic-quadrant-for-integrate-266749-2.pdf. IDC has the same opinion: http://www.idc.com/getdoc.jsp?containerId=prUS40861015
I tend to agree that all three categories will still be around in 3 years.
