Unfortunately, this year, New Years eve is on a Saturday night, so no one is really forced to do anything extra or out of the ordinary, or go any longer than their usual timing. Maybe extra stations that don't normally mix may decide to do something for the night, but that's about it.
Fortunately, next year is a leap year, so New Years eve in 2012 for New Year 2013 will be on a Monday night instead of Sunday. So, if the world doesn't end beforehand, a lot of stations may mix Friday night into Tuesday. If 2012 wasn't a leap year, New Years Eve would've fallen on Sunday next year.
