Modern management and security principles driving our Microsoft Endpoint Manager vision

I'm one of those customers not using Config Manager. Brad Anderson, in this blog and on an appearance on Microsoft Mechanics, said that we can move straight to Intune. I can't find any documentation supporting running modern management in Intune alone. All documentation found so far discusses co-management. What is available now just running Intune and what is promised for the future? Can we get desktop telemetry for desktop analytics without config manager, for instance? Can I get the richness of desktop information without deploying config manager. I know as an E3 - EMS - P1 customer we have rights to the config manager software (although I've seen some postings where customers can't find a Microsoft person that knows this without referencing some internal document number). I would rather simplify things and not have another server on-premise doing what I hope Intune can do under it's new banner Microsoft Endpoint Manager. Brad, I hope you clarify what we can do today with cloud only based Microsoft Endpoint Manager.
