Wikipedia has a list of all serials (specifying missing episodes) and of the DVD releases.Is there a List/resource guide that lists the stories in order, how they're released (Or not), and what's wrong with the ones not released?
I hope they animate all missing episodes, if the current animation is too expensive, they should switch to cheaper animation or cheaper animation studios. It really doesn't have to look perfect or even close to the original footage. I appreciate the effort seen in the first post, but not if it prevents other animated episodes from being made.
There's nothing wrong with simplifying the character models, using less details on the costumes etc., the most important thing is to actually get the episodes made, so that they can be watched again.
