Cartoon Wars- Did Comedy Central Puss Out?

The general reaction in the blogosphere seems to be that no one is quite clear on what happened at the end of last night's South Park episode. Did Comedy Central pull the plug on the depiction of Muhammad, or was it done purposely by Trey Parker and Matt Stone?

Who would have ever thought that South Park would become too smart (and as the episode self-mockingly pointed out, "too preachy") for us all.

Update (2:10 PM): It looks like Comedy Central did puss out. More power to Matt and Trey.
