well the writings been on the wall for a while. I don't know the specifics but the show has not been renewed for a third season. And if it had we would have heard it by now.
Maybe it was all the hiatuses or simply poor toy sales (Toy deals are the banes of a lot of cartoons), but regardless looks like this shows axed. So enjoy this season looks like its all we are going to get
At this point I'm not sure if there is anything that can be done to save it. Maybe some massive fan outcry and petitions, but it would have to be a lot and I mean a lot to even hope of getting the networks attention in a meaningful way.
