Alex,
This new keyboard, as I've been told, is not to replace the SD1+ 76 key flag ship model. This is a keyboard which will be priced about the same as the current XD9 but will have more buttons for the player rather than having to go deep into menus. Because I am a dealer, AJ couldn't go into much detail when describing this new model but was very excited because he had a lot of input in it's creation. The styles and layout are much of his input.
The replacement for the current SD1 is not coming at this NAMM show.
