does anyone know when this badboy is supposed to come out and how much its gonna cost? it supposedly has like 145 hour playback from one battery :O but its prolly gonna be pretty expensive. i could only find specs on the net but no release date. can anyone help me out?

on another note do you think the Sony MZ-N1 ($599) is worth the extra $200 than the Sony MZ-N707 ($399)? (mind you this is canadian dollars).
