Here's the actual article from VMWare:

It sounds pretty unambiguous; they go out of their way to note that these products are no longer available by any means and are discontinued, and they list both vSAN and NSX.
But, yeah, just because a company says something doesn't mean it's true, I guess - wouldn't put it past them to say "oh, all these products have been replaced by the new VMWare vCloud Platinum MAX offering" which is just the same products in a bundle that costs ten times as much.
