Given the amount of crap NC has done in the last five years, you could atleast assume that he wouldn't have knocked back the work if the opportunity arose so it has to be down to the powers at be. I would've thought Cage would've been pushing for a new NT in any way he can given his past crap....NT is the only thing he has going for him these days (in my opinion anyway) (and as Brad says, it's been almost 5 years but if they do it right, I could be great fun.
The only concern I have with an NT3 movie is cost to me. If a new movie is indeed made....it's a stick on that the talented NT heads of the RPF will no doubt start offering a load of cool NT stuff to buy. I've not even finished my NT1 collection yet!
