Gem i beleive are still in business. The new product talked about a product pitched around the yamaha psr900 price. It has a black case and has a full colour display with mp3 playback etc. the product all be it no where near completed was shown to a selected few me included at frankfurt 2008. the case look a little similar to the old WS2 keyboard black in colour.
Knowing Gem what they showed us will most likely change anyway.
