Kurzweil has had a number of arranger-type boards for a while, under the guise of the piano-type home instruments. They sound pretty good, but not as good as K2600; they don't have expandable/editable sound set or built-in sampling. The number of styles is fairly small - IMHO they lag behind the top-of-the line offerings from Yamaha, Roland, and even Technics. They are also way too expensive for me.

I hope the instrument Ilija is talking about is a portable keyboard with many of the features of K2600 plus auto-accompaniment styles, rather than one of the home-keyboard piano-type insturments.
