Looking at the comparison chart Zimbra - Compare Products

I noticed an innocuous change that may have a big effect on my license costs. In the past, in ZCS 4.5, mobile syncing was an addon cost. In ZCS 5, 6, and 7, it was included with ALL network licenses (Std and Pro). But now it seems that ZCS 8 will only allow pro licensed accounts do mobile sync. I have paid for 3 years for a combination of Std and Pro licenses with an expected level of service. The difference being that only a few people actually want to sync Outlook, but almost everyone wants to sync their phone. Now it seems that I will need to upgrade all of my Std licenses to Pro licenses if I want my Std licensed folks to continue having mobile sync capabilities. Am I correct in assuming this to be the case?
