A professional wedding photog friend of mine shoots film exclusively. He uses a 35mm for photo journalit style stuff during the reception and uses a host of Hassy equipment for the more formal shots. He says that as long as he can still get film and decent, reliable processing, he'll stay with film. Interestingly, He says that he actually caters to a higher end of the market now - seems film based photos are recognised by some as superior and worth the extra time and money. It's all about marketing.
