It'll be interesting to see how well customers will adopt this. When I was at one of the two companies you mentioned above, we tried adding global snapshots (a la TrueTime, which is the real innovation in Spanner not the clocks) and demoed it to our DBAs/MVPs. They didn't understand what on-earth was going on. Wanted something that worked with existing clients. We just gave them classic 2PC and they went home happy. I think that's the reason why Oracle will keep on chugging. There just aren't that many workloads that need this sort of scale. It is real cool technology though and we always used to wonder why Google wasn't offer Spanner as a service.
