In his AmiWest 2012 presentation (direct link, Youtube), Trevor kind of reveals that there may currently be 400 to 500 X1000 owners. Whether this is meant to include those buyers from the current batch who still have to get their machine (supposed to be delivered until January 2013 at the latest) is unknown to me.
