Waw!! this sounds like a winner.
I hope that sampling and hard disk recording will be available some way on this board. Being able to have samples on user styles to me are becoming essential for music performance and production today.
Also I hope it has sound editing.
I am glad to hear that it is not just an arranger but also has a sequencer.

Hopefully it will be a reasonably priced board and the weight will not be on the heavy side i.e. over 40 LBS.

This may be a contender now that I am looking to get back a 76 key keyboard.
