If any commercial network picks up Letters and Numbers, I think it'll be on Ten at 6pm. I can't see the program on Seven or Nine because L&N is too smart and sophisticated for "The Big Two" IMO.
If a commercial network is smart, they'll snap them up.
I personally think that it would be somewhat amusing to see Letters and Numbers on as a lead in to ABC News, knowing that the programs host, Richard Morecroft was once the presenter of ABC News NSW!
Maybe they should shop it around to ABC. They could do with something decent at 6.30pm for instance as lead in to the news.
