Numb3rs: Season Ending episode = SERIES Ending episode?

TV Arts

They sure are wrapping up most everything, maybe it's a case of 'we
aren't sure we are getting renewed so...'.

They were told last Fall that this would likely be it, especially with the 
cut in the episode order and the early ending. It was on the bubble last 
year for renewal. It's only been since December iirc that CBS has been 
hedging on whether it'll be picked up for another season. That season/series 
ender was done so they could go either way, it seems. I think all the nets 
may be looking to save cash by not programming Friday with scripted 
programming except reruns. Even USA abandoned the night this year for their 
original run programming.
