Not that it matters now but I just read this at Troika Chronicles: I find this interesting because I thought that Tim's stance had always been that he didn't like sequels (I was going to put a link to an interview on our main page here, but it is currently unavailable). So, even though it never got made it was actually designed.
So which one does he really believe? BTW thanks for that mathboy, I've read that interview on our page before, I'm sure of it, but maybe I did read it at Troika Chronicals.
