Laura and Max have a one year contract right now.  It is possible that year could be extended, but they also owe NBC a year of their life after "Grease." So we will all have to wait and see what might be happening about a year from now.  NBC could elect to use them or not, someone could maybe buy NBC's right (I'm not sure), or their year to NBC could get pushed back later to potentially work longer on "Grease."  It will be interesting to watch.
