For the record I got my tickets this morning, so they should be rolling them all out now.
EDIT: heh, mine is the O2 empire ticket.
EDIT2: Just a thought, sanorin, your ticket just says general admission and seat, so doesn't that mean you'll be able to choose any tier, any seat? Whearas mine says level 1 unreserved, seat. I'm just saying I know your face don't steal my seat heh. (Joking). Though I just hope they have done this venue transfer correctly and no one gets dissapointed.
