On the corporate websites (Chrysler, Dodge, Ram, etc.)... at the bottom right, where they display the corporate logos, Ram is shown as a separate logo, along with the logos of Chrysler, Dodge and Jeep. The implication (to me, at least) is that Ram is now a separate nameplate/division. Don't know what, if any, difference that makes to the consumer.
But then again, Chrysler has always played fast and loose with their own brand identities. They sold Chrysler Imperials, then just Imperials. They sold Dodge and Plymouth Neons. Who knows where this new Ram thing will eventually end up?
