it's really an upgrade to the 80, not a replacement for the PA1x (THAT will come next year imo , maybe at summer Namm) although i think that some of the things on the 800 will find their way onto the new PA2??X....like the increased poly and RAM and the 3 USB ports (one is a host port)....price is believed to be at $2500 Euros...the keyboard guy i deal with has just returned from a dealer demonstration day with the board, and he was mildly impressed...speakers are good, some new styles, it's got the TC Helicon vocal processor..NO option for the MP3 board, and the HDD is an option...bottom line if you have a PA80 you would upgrade but not if you have a PA
