Vic,
Stephen Kay has said there will never be a rack-mount Karma. There has been no hint of any new Karma hardware, although SK was receptive ideas of a Karma arranger and a Karma tabletop (like Emu-XL-7). My reading is that SK is focussing on software for the Mac, of which three versions have been discussed. I expect some software to show up this NAMM. A lot of people have been asking about a PC version of the Karma software, but I think SK is not that interested in that project, so the PC version may be far off in the future. We will know more next week of course.
