Glenn,
The Ketron keyboard we will see at NAMM I was told will be their lower end keyboard, more to replace the XD9 rather than the SD1. Later in the year, I was told, we will see a higher end keyboard, to replace the SD1. None of this is more than a bit of information I was told by someone in the know, but this was several months ago and we will have to wait to see if I'm right or wrong.
