This was released on the Tcats Facebook Page and they also put up a better looking trailer. I don't think it's new material, though.
In the comments for the trailer, a lot of fans appear to be ripping the show a new one - before even seeing it.
I'll wait and decide until I see it for myself but, imo, the animation looks great (way better than the new Voltron!) and Snarf is not going to be an annoying whatever the thing is!
Good news in my book!
