ETA for Japan availability of --orchestrator-version

[lostllama]

We've been forced into using ACS due to lack of availability of AKS in the Japan region.

The problem is, Azure creates the cluster with Kubernetes 1.7.7 and we want to use 1.8.x or 1.9.x because our project uses deployments, which were in beta in 1.7.7. We were overjoyed to see --orchestrator-version in the list of parameters for az acs create, but soon realised that it's only available in a seemingly arbitrary list of locations (including Korea) - a list which doesn't include Japan.

At the moment we're stuck using 1.7.7. When will we be able to create a 1.8.x, or 1.9.x cluster?
