And you hate when things go to Netflix.
Thing is, it was always like that, but with that new edge of "kids don't watch TV anymore." I don't see why this couldn't be internet content (not so much netflix, but more like CN's Mighty Magiswords), other than budget reasons. CN clearly has no desire to have more than a few shows in production at a time, and something tells me they'll use every excuse in the book to not get another series picked up until several of them end. Given the fact they screwed over Uncle Grandpa so badly, not to mention their Scooby-Doo and Wabbit cartoons they fell over themselves to promote.
Now CN has had a lot of trouble when it was revealed that they refuse to make cartoons that girls would like because girls don't watch cartoons (no thanks to everyone still thinking it was 2005 Disney Channel...seriously, *&^% those shows), and that's why every DC comics based cartoon besides TTG was dropped like a rock (and the fact the toy lines, if any, Suh-diddley-ucked). I wouldn't be surprised if that was the only reason PPG got the "reboot" (it's a freaking continuation and we all know it). To try and mend fences with girls, but using something recognized and established. Something new would probably scare away viewers (bullcrap, since by all logic every cartoon they greenlit is "too weird," Cow and Chicken especially) and probably not generate a crapload of merchandise they couldn't get a toy company to produce.
Yet, toyetic shows like Transformers and Sonic Boom are shoved off into death slots. Guess if they don't get a slice of the merchandising pie, they don't give a crap.
And I reiterate...this is why more cartoons are going to netflix and the like. I don't think any of the small amount of kid's networks (there are more ESPNs...and they're all losing Disney money) would touch any Dreamworks cartoon series, especially Voltron. And given how Nick treated DW's shows (Penguins and Kung Fu Panda yet have episodes to air despite being wrapped for years), I very much doubt they'd want to screw with network interference again.
