If you mean a large capacity player true second generation Karma, then no, it never happened.
In the vibez, the Karma's interface and software features definitely evolved but in a much smaller package. The vibez lacks the RCA out and ethernet features of the Karma's dock, and it tops out at 12 GB of space vs. the Karma's 20 GB. Which one sounds better is debatable, but the Karma definitely has a strong headphone amp.
Just about all the software-based stuff is there: The EQ, gapless, Now Playing list, etc.
