No reply from CBS, but two sources tell me CSI: will end (http://deadline.com/2015/05/csi-tv-movie-series-finale-1201423421/) its legendary
run on CBS next season (http://www.ew.com/article/2015/05/08/csi-final-season) with a two-hour movie (http://www.tvinsider.com/article/1707/cbs-mulls-wrapping-up-csi-with-a-2-hour-tv-movie----could-william-petersen-return/). (1/2)
