I didn't say anything about them shutting down the services, I said they were "silo-ing" them and clearly moving away from having them interoperate with 3rd party software. It is not at all irrational to worry for how long your enterprise users' contacts and calendars will continue to sync. They've thrown us a lifeline for the time being and even appear to be working on a fix for Outlook 2013 so it will sync (it doesn't as of right now), but the whole process of sunsetting support for ActiveSync then CalDAV completely tips their hand that they want to control who and what interoperates with it - and for how much longer it will interoperate with platforms beside their own Android core PIM suite =| the entire mobile and desktop universe. There are people paying for Google's enterprise apps offering that don't use Android. What is in question is for how long core services of those apps will work outside of a browser/Android device.
