Oh okay because they haven't made any announcement that Heroes was gonna go on a "break." I thought Heroes wasn't affected by the strike.
Everything is affected by the strike except news and some cartoons. Fox's animated lineup
is affected, but they tend to be produced so long before they're made that it won't be an issue. South Park would probably be a sticking point, since it's produced and written the week of, but their season is over anyway, and I'm not sure if they're WGA shows.
The thing with television and movies is that everything is controlled by the guilds. And in a year, the actors' and directors' contracts are up for renegotiation, so if the studios really want to be bitches, they can make it happen again.
