I had a similarly bizarre date explained to me (on the phone! Amazon do occasionally answer, although they don't like you to find the number in the first place) as 'the date the computer defaults to if it can't find out a real date or something hiccups in the order process'. This is a constant date, unchanging for about nine months, and they eventually change it when they get to it. Could be that 29/1/06 is the current default date, since I have two items also showing that (due for release in Feb and March respectively)?
