Thanks to Ben for this - This is the reply he received from Tom Kirk when PM'ing him on the official muse boards.
hi ben. yeah earls was great and we did have cameras rolling. it takes a long time to edit and the timing for release of a dvd has to be carefully planned. its in discussion as to when we will release the next one. sorry cant be too specific. you'll see it one day though!
Good news, hopefully :)
