Hi Scott
Just because Yamaha do not import their Electones (Organs) into Europe or the US any more does not mean the organ market is defunct.
As far as Electones go they are as popular as ever in the Asia market, and are constantly being imported into Europe by uses who find arranger keyboards too limiting.
New models from all manufactures are regularly released, with 4 manufactures releasing new models in the next few months. (Roland are releasing an entire new range)
Enjoy whatever you play

Bill
