When will the CMC updated with AI7?

By looking at youtube I was noticing, that a AI7 is preparation. (“Cubase LE AI Elements 7 - Quick Start Video Tutorials - 1 – Setup“).
Since I want to buy a new CMC device I wanted to ask, when does the AI7 is published.
Is there any information about upgrading AI6 versions to AI7 or some “grace period” style?
