Keep this link handy:
link That's the site I go to a couple times a ماہ to check out the renewal/cancel index for the show. Right now, CSI:NY is still up in the air and can go either way, though it's up .05 points from where it was the last time I saw it. You'd be hard-pressed to find anymore information out there better than what this site has. TVbytheNumbers has the best prediction ratings in past years, so I'd definitely keep checking back from time to time.
I hope that helped a little bit.
