With the fall TV season almost two weeks under way, pickup orders are starting to trickle in. Among the first beneficiaries are Fox's Prison Break and American Dad and NBC's The Office. Each of the Fox series has been granted a full 22-episode commitment raising the question of when Prison Break's nine added outings will air, as 24 takes over the time slot in mid-January  while NBC's workplace comedy, now in its second season, has been greenlit for at least 13 outings. Also reaping renewals: USA Network's The 4400 will start production on a second season this winter and  the one you've been waiting for  WE's Bridezillas will premiere a third season in March.
