I'm still confused as to what the official problems and the actual problems are.

It sounds like, officially (from TakaraTomy) is that some of the sound clips are mixed up and the packaging has some errors... but the actual reasons, which TT may not want to publicly admit to, include physical QC issues and sound clips used without permission.
Is that just fan rumours or is any of that true... because I can't believe that some mixed up sound clips and minor packaging errors would warrant an expensive recall and refund of these big expensive boxsets. If that was all that was wrong, most fans would still want the toys, and after a little bitching about the minor errors, the toys would still be worth owning and playing with. Because what if they decide against doing another production run, as those who don't return their toys won't be buying from a new production run, reducing the demand enough to be too risky to make more.
