Where did you get the idea that the XW-G1's street price is $799?
The XW-P1's list price is $699,with a street price of $499...so the XW-G1's list price of $799 is going to translate to $599.
Besdies which,the street price of $599 for the XW-G1 has been confirmed by Mike Martin,who works for Casio.
From the Casio demonstrator at NAMM 2012. If the street price ends up being lower so be it. But I had posted that just after talking to the Casio rep at NAMM. Surely you didn't think I just made it up.
