There is some news about the IDW TMNT comic. IDW has renewed it's license for the comic, so it's not going anywhere anytime soon. But, it seems like Sophie Campbell's leaving after issue #150. And it sounds like we'll get getting a new #1 issue sometime in the future.
This article has some interesting quotes from some of the past creators on the book, celebrating the #150 issue milestone:
Teenage Mutant Ninja Turtles hits #150 in April, and IDW Publishing has confirmed that the double-sized issue will be the finale..

This article has some more information about the license renewal:

And this article confirms that the new series will NOT be a reboot. It sounds like the new book will still take place in the same continuity as the rest of IDW TMNT:
Sophie Campbell's Teenage Mutant Ninja Turtles run may be ending, however, IDW Publishing says more TMNT comics are on the way.

I'm a little surprised, but kind of glad that they aren't rebooting. They've already done so much in this universe already that I'm not sure what else they can really do. Shredder's reformed (for the moment), they've beaten the Pantheon, they've already been to space and alternate dimensions...they've kind of covered everything TMNT usually covers. But, I'd kind of miss the IDW TMNT universe if it did end. So, I guess we'll see how they manage to continue it. I'm curious how they'll manage to keep it fresh.
