I'd be surprised if Azure Stack sees big adoption any time soon; they aren't just letting you run some Azure services on existing hardware... the way they're doing it is to really take the "cloud in my datacenter" concept to the extreme:

* Subscription pricing like a cloud service, even though it's on-premise.

* Only runs on certified hardware appliances... You're looking at an investment of at least $300,000 for a base configuration.

So, OK, I get it, you're getting a private cloud and you're not supposed to worry about hardware anymore, but it's probably too big a mental shift for most traditional enterprises. And people with that kind of budget are already locked into a VMWare infrastructure for the next couple of years.
