The decision has not yet been made regarding the series' fate. They're waiting to see what the early buzz is regarding Salvation.
The buzz(pre-release) is good.
You must mean they are waiting on its OW haul.
Still the TV show is so unrelated to the events in the movie continuity its a moot point anyway. At best FOX might see an episode or two spike should it return for the Fall but unless it somehow retools it'll just drop back off.
