Feedback re: how-to panels w/ GoH

[GokuMew2]

Hi everyone!

For the past few years we've had some how-to panels with our guests of honor, including:
-General Anime Production (Yumi Sato, Animation Producer / Takahiro Omori, Director / Hiroyuki Kanbe, Director)
-Storyboarding (Kazuhiro Soeta, Storyboarder/Animator)
-Character Designing (Yoshihiro Watanabe, Character Designer/Animator)

These panels have proved to be quite popular with attendees. What other aspects of (Japanese) anime production would you guys be interesting in learning more about? We've hosted several Japanese voice actors in the past, but would people be interested in procedures such as how voices are cast or the actual recording process? What other topics related to the creation of Japanese anime would people want to learn about?

I can't guarantee that we will be able to get guests who can host these types of panels, but I would like to gauge the interest to see if it's worth looking into. Also, would people be satisfied with someone who can explain the processes but doesn't have a long list of popular credits? Or would the guest's credits (or lack thereof) sway a person's decision on whether or not to attend their panel?

Thanks in advance!
