The Futon Critic has a post confirming ABC episode orders and reports that the total order for "V" was cut from 13 hours to 12, and the "FlashForward" order from 25 hours to 24 hours. More info on ABC episode orders via Futon Critic.
Shout out to reader "Don J." who hammered the point home that more than a few people might be interested in this. I saw this news earlier but elected instead to post, about..."Chuck".
