Openstack was originally developed by RackSpace - which is a major ISP - and NASA, which generally doesn't fool around when it comes to computers. Among the current supporters can be numbered Red Hat, IBM, AT&T, RackSpace and HP. PayPal supposedly runs on OpenStack and a number of other major companies use it to a greater or lesser degree.
So I'd say that there are some serious production use cases out there and have been for some time now.
Often the most important part of the news is what they didn't tell.
