The future for TMNT hasn't been looking bright in general. Nickelodeon bought the rights to the series. There's supposedly a CGI cartoon coming in 2012. Kill me now.
I'll be honest, I thought that the CGI movie was decent. My major complaint was that it really shafted Donatello and Michelangelo and focused mainly on Leo and Raph.
Also, I know I'm about to get shot for this, but I will personally always see the 2003 cartoon as infinitely superior to the 80s one. Probably the only good thing 4Kids ever did, but that's probably because one of the original comic creators had a say in what went into that series. It was darker and edgier, yes, but that's how TMNT started. The '03 verse is closer to its original roots. It did stray off into filler and season six and most of seven should have never existed, but even so when it was following a solid story, it did a great job. Plus not all of the filler was horrible. It was a nice contrast to the goofy toon of the 80s. If anybody ever watched Turtles Forever then you can see a pretty awesome (AKA hilarious) comparison.
