DocArzt from Thetailseciton.com dropped me a line about finding an article in Mediaweek that quoted Stephen McPherson, who is of course the president of the ABC Entertainment Division. He's the one who that back in July of this year had an assistant call Damon Lindelof in the middle of an ABC TV Critics press conference back a day before Comic Con 2007, so that he had the okay to leak information on a now well-known casting spoiler for Season 4.
Well the current news is that he was chatting about ABC's lineup for Season 4, and the female viewer demographic, and the point is that Wednesday nights seem full with other shows. He also specifically mentioned ''Lost'' as a "wildcard asset", meaning we may see Lost broadcast almost any night, maybe (or maybe not) the Monday 8pm slot that has been rumored lately.
The Mediaweek article is mostly a long snore on demographics, so instead hop on over to DocArzt's summary at Thetailsection here.
