Re: Wait, didn't this already happen?
That's exactly what happened.
Par for the course, announcements announcements announcements. Then pretending as if it is a feature for months, then finally a public beta sold as production ready. You got to give it to them, they have great marketing. The press would tear any other vendor to pieces but these guys get a pass.
All their announcements compete with established players in their respective markets: NSX, RightScale, Veeam, Scality, and so on. All of them needed years and hundreds of customers until their products were really ready for prime time. Yet Nutanix announces they are doing [X] in a few months and El Reg creams their pants and proclaims it will be the best product ever.
