Well folks, here is my judgment after owning and playing with my Genos for a week.  It is a Yamaha with Yamaha voices and styles - simple as that.  If you expected Korg-like or Ketron-like sounds you will be disappointed.  The voices are pretty good and the styles are suitable for most music.  The old styles that have been re-voiced are also nice.  It would have been nice if Yamaha had replaced them but that is the way it goes. I upgraded from a Tyros 4 and find a very big improvement in sound overall.  
Yamaha did add some nice features to the Genos that will make gigging easier and song set organization easier.  
I have to agree with Gary, many of the forums are full of posts by people who have never touched or seen a Genos griping about what is or is not present in the Genos.  They gripe about sound quality of recordings by people trying to show a little of what the Genos can do.  I wonder if these folks understand these videos are not being produced by professional film makers who own or have access to high quality recording equipment.  Frankly, I took all my videos down and have been a little disgusted with the reaction of people who seem to have nothing better to do but gripe.
