Re: Who or what could ever be trusted that much?
Nail on the head.
I can tell you how the pieces are aligning. I can't tell you yet who will win, or whether open standards (read: OpenStack, most likely) will win. I suspect that if two proprietary IEMs appear that are mostly interoperable (where "interoperable" can be achieved with some minor conversion of automation/orchestration runbooks between the IEMs) then enterprises won't care. They only ever needed EMC and Netapp to play off one another, (or Oracle, DB2 and SQL)...why would they need more than two, possibly three IEMs?
Interesting few years ahead...
