The premise behind Adobe's Creative Cloud and Document Cloud products is that Adobe will be offering updates incorporating both new features and bug fixes on a fairly regular basis as these features are developed and fixes made. For some of the Creative Cloud applications, there were CC followed by CC2014 versions. After the CC2014 versions were released, no further updates were offered for the CC versions. For the CC applications such as InDesign, Illustrator, and Photoshop, though, you can get away with having parallel installations of older and newer versions (such as CS6, CC, and CC2014) until either the OS no longer supports them or you feel comfortable without them.
What I can tell you about these applications is that you will continue to get updated applications, but whether it takes on new moniker such as CC2015 or CC-Fred, that's more of a marketing call. (I'm just a dumb engineer here; I don't have input into or insight into that process directly!
)
In terms of Acrobat DC, per other parts of this thread, you
cannot safely have more than one version of Acrobat installed at one time on a particular system due to interfaces that Acrobat has with other applications, drivers, etc. But the plan is that subscribers to the full Creative Cloud (not just single applications or the photographer's option of Lightroom and Photoshop) or the Document Cloud will be offered updates to Acrobat both in terms of features and fixes on a regular basis. (Note that licensing Acrobat with a perpetual license will provide feature and security fixes going forward, but not additional features). Whether there are subtle changes in the names similar to what the CC applications have is not yet determined.
Clear as mud?
