There's nothing implausible about planning. 4kids needs to plan for the long-term. Again, animation is something that has a long turn-around time (Young Justice is fast by animation standards, about 1 year from pitch to airing). 4kids two years from now might be in a far stronger position than they are now. That's when the property needs to be ready.
I know animation is expensive and each episode costs hundreds of thousands of dollars if hand-drawn, and possibly even more expensive rendered in CGI. That's why networks commission pilots, so they know they can blow 4 million or something on 13 episodes.
Even if 4kids orders 13 episodes of an original property now, it'll still take eighteen months before it's ready to air. There's conceptualizing, writing, etc. The most expensive part is the production part where the voice acting, animation, SFX, etc., come in, and that doesn't start until six months or so before the series airs. Heck, Young Justice's rushed production schedule says a lot, the first season is STILL in production even as Cartoon Network blasts through episodes. As episode 1 premiered, episodes 7-9 were being animated. And guess what, episode 7 is airing this Friday.
4kids should have something in pre-production so if their situation starts looking up they can quickly get 13 episodes out the door. And if Toonzai stagnates, well, how much money is wasted in pre-production? Much less than if the show actually went into production or post.
