Hi all,
Uh-oh: Musician's friend website lists the XV-5080 as expected in stock in mid-September (!).  Not a good sign, as everyone was expecting the 5080 in stock "sometime in June", last I heard.  
(It appears Roland has learned something from musicians about being fashionably late, starting the show later than announced, just to let excitement build.....)
Maybe all you other prospective buyers can use this spot as a point to compile when/where they start to hit the streets.
Thanks,
Christopher
