I think that they will release a new M model synth first... The synth should yhave an improved sound engine, Karma 3+ and hopefully be able to run the EXi's developed for the Oasys. (would be very stupid from Korg not implement them as they have those programs readylli available without much effort, after all its software)

I also think that there will be advanced options to controll VST's running on a remote PC.

Then a few months later some of this technollogy should find its way intoo a new PA. Maybe even supporting audio styles.
