Although GEM is in the ELKA currently they are in the works for an arranger,rumor has it and we will see,and I have the GEM WK8 which is the same as the sk880 my opinion is that the GENESYS was still the best of them all,there were alot of features that were finalized on the Genesys, just to name a few on the WK series the midi outs were closed and the drums were not as good as I would have liked.
