I haven't seen any of the new cartoon because I don't get Hub network, and I haven't bothered to watch it online. However, I think it's kind of shady to drop a show because it may interfere with a live action film that, as far as I know, doesn't even have a script yet!
The toys, on the other hand, are a little different. Where Star Wars can support both movie and animated toy lines, I don't think the base is there to do that with Joe. I could see Hasbro not wanting to divide the market when the inevitable toy line hits for the film, but that shouldn't have an impact on the cartoon. I don't see any of the the Marvel or DC comics and/or toys suddenly stopping production because there's a big screen film of their main characters about to open. ****, it would have been a GOOD thing for Marvel to have Hasbro stop putting Iron Man figures in the MU line while the IM2 line was in full swing, but they didn't.
And maybe I'm wrong on this, but it seems that of the boy toy lines Hasbro actually owns, Joe and Transformers are the two best suited to a cartoon. Why would you create an entire network and then put one of your best options for a show on hiatus? Bad ratings, maybe, but since you own the damn network, I'd think you'd take more than one season to try and build a fan base. I'm trying to think, but other than maybe in the comics or on the toys, I don't believe I've seen any advertising for the cartoon...maybe Hasbro should spend a couple bucks on promotion.
