The Renew / Cancel Index has had Blue Bloods, CSI:NY and The Good Wife in the "toss up" range nearly the entire season, now forced to guess, I'll take the chances of The Good Wife over the other two.
I'm fairly certain that two of these three shows will be cancelled: Blue Bloods, CSI:NY, Criminal Minds: Suspect Behavior, but no combination of two of the three being cancelled would surprise me.
Although it's outside the bounds of the Renew / Cancel predictions, I'd be very surprised if Two and a Half Men doesn't return in some fashion.
For those who'd like to review the last Renew / Cancel Index numbers I'll produce for the season, enjoy:

The Renew/Cancel Index is the ratio of a scripted show's new episode adults 18-49 ratings relative to the new episode ratings of the other scripted shows on its own network. It's calculated by dividing a show's new episode Live+Same Day adults 18-49 average rating by the Live+Same Day new episode average of all the new scripted show episodes on the show's own network. The network's average ratings in the calculation are not time weighted (ex. hour long shows are not weighted twice what 30 minute shows are).
(F) -Fridays: Shows airing on Fridays were renewed with significantly lower than average Indexes.
