Seems to be what Sony typically does as they phase a product out. A new flagship coming? The EX700 is getting old and Denon, AT, Panasonic(most of their other Japanese competitors) have brought forth new models. Sony and Victor have gone quite long with the EX700 and FX500 as their top of the line.
Maybe an EX900 moves in at the $300 price point and the EX700 stays but at a lower price?
