I had a Karma keyboard along with a Triton pro a few years ago in my band days, great instrument for live use and recording and it gave some inspirational ideas when using it.
It will need to be changed a bit to get near auto accompaniment in the top arrangers, but I'm sure Korg could do it sooner or later. An OASYS with auto accompaniment would be amazing.... pretty please KORG as long as it's not about £10,000
