No, but you may be right. And I really hope they aren't going to leave us with a total cliffhanger especially when the chances for a pick up don't look good at all. They've been pretty good about giving us nice finale eps so I hope they don't change the program.
Ausiello posted an update in a post about other pickups on 10/19.
"Oh, and the Chuck back-nine news I reported yesterday? It’s now official, only I’m told it’s actually a back eleven! That’s right, Chuck‘s fourth season will be 24 episodes long!"
I enjoyed Monday's episode, but I expect others to be stronger. They had so much to setup for the season (almost like a pilot) that the premiere suffered a little. I'm just happy to have it back. It is one of the most enjoyable shows I watch.
