PeteMitchell I hear you, though I don't think Microsoft ever viewed E5 as the everything-package. Adding E(>5) almost inevitably would mean all improvements going forward would not be included in E5, which betrays the original subscription vs. traditional licensing model: you pay monthly rather than an ad hoc 2-3 years--maybe skipping some releases--but improvements and upgrades are now included. That ad-hoc-licensing ship sailed years ago, but Microsoft can't turn around and start charging extra for continual improvements and upgrades: that was a core part of the value proposition to switch to subscription in the first place.
However, I still think Microsoft also can't be expected to include everything in E5 (and they haven't from the start of E5, really--just like Visio and Project haven't been part of Office, Dynamics is several separate things, LinkedIn has several services, etc.); they need to have flexibility. Nonetheless, their pricing with some recent offerings--particularly pricing relative to value (e.g. Remote Help, Scheduler
, etc.)--is just completely out of whack.
