I dont think the bold bit is correct. Lightroom desktop CC and lightroom CC will both be cloud based. The difference will be in the interface. Desktop is current setup and the other is geared towards tablets and mobile devices. There wont be a standalone version after the next update to 6.xx
there is a bit of a confusion going on in terminology, we are saying the same thing...when I say Desktop version, that is Lightroom Classic, it uses your computer for file storage, not the cloud. So it is as close to standalone as Adobe will have going forward, it is part of the Creative Cloud yes, but it does not use the cloud for the app or file storage. If you still want to keep your files all on hard drives, then Classic is the way to go.
