Are there any dates for it to come out. I went to my dealer and they said that it should be here very soon acording to shindaiwa. Is it anymore powerful than the 8510 or is it only going to have the new back support on it. I hope that it is like leather seat backs with a built in system cup holder and cooler. Wouldn't that be great. I am so satisfied with my 8510 I can't see how they can make it any better. i am so excited I am going to go to the dealer when it comes out to try it out for em give it a little test drive.
