When I was watching the episode with closed captioning, Muhammed's name was uncensored in the text for about 2/4 of the episode. During the second half, any referenced of Muhammed's name was spelled out as [bleep] on the closed captions.
All in all, if South Park ended today (which won't happen anytime soon, since it's Comedy Central's highest rated show and biggest cash cow), I would pretty much be satisified if it was going to go out with the "201" episode. We got all of these resolutions (such as Cartman's real father's identity) and character returns (e.g. Scott Tenorman, Pip, Mr. Hat, the Super Best Friends, Dr. Mephisto, Tom Cruise, Rob Reiner, Barbra Streisand, etc.) after 13+ years of build up.
