Exchange Server Roadmap Update

Thanks for the update. It's pretty much as expected however pointing to SharePoint Subscription Edition is something I hope the Exchange team DOES NOT rely on. That is an information conveyance disaster. SharePoint SE documentation is still wholly incomplete on what exactly is needed for a company deploy from a licensing standpoint. I believe Exchange team can do this much better! Please provide comprehensive directions in the very near future of exactly what is needed to deploy Exchange Server SE including if we will be required to have existing Software Assurance for base products. Which CALs are required and if Software Assurance is required with them. I'm not concerned on pricing, but it's now impossible to ask even the largest MSPs what is required license wise to license SharePoint SE and get a consistent answer. Don't let this happen to Exchange server SE please.
