And there's already multiple tests made featured here, of this studio making the first, very expensive CGI animated feature film which might've had a slightly different precedent set. I feel like you could say that "there might be more we don't know about" about a lot of things, like animated commercials of a specific mascot character. But there's a difference between that and having evidence or suggestion that there actually are more tests out there, when those could've been featured on the Ultimate Toy Box DVD if that was the case.
