Why shouldn't it be theatrical? I would love for this to succeed, as American cartoons released to theaters that are based on currently-airing cartoons rarely do, unlike anime movies in Japan. The Simpsons, South Park, Beavis & Butt-head, Rugrats, and SpongeBob are the only exceptions. The MLP movie released in the '80s was largely a flop, so hopefully this would would buck the trend (no pun intended).
