When they remove the "broken track" piece from Expedition Everest, and it becomes truly scary!! http://youtu.be/DHK3NLOfMfU I'm assuming they're going to replace the missing piece, as it looks like they've already replaced all the raggedy, worn Tibetan prayer flags with new ones. Hopefully they'll fix the broken bird effect while they're at it. Of course I don't suppose there will be any changes to Disco Yeti...
