It makes sense moving forward adding a whole new set of capabilities to an already powerful stack of tools and services. Can't wait!
One clarification about the Premium licensing that should be made by Microsoft is around the statement "Project Online Premium subscriptions remain targeted at Program and Portfolio managers." This causes a little confusion among customers and their understanding of how many licenses they need and for whom. In other words, only a single Premium license is necessary for provisioning PWA instances which provides the licensed Essentials users with full Program and Portfolio Management capabilities yet the statement implies multiple users will need the Premium license. Moving forward is that subscription/pricing model changing in any way with the new Project being built on the CDS for Apps platfom?
