Since this is my first con, I can't really comment on what
should be added this year to make it different.  Though
all the topics you mentioned sound good.  Maybe you could
possiby talk about cel restoration?  And possible US
dealers, since it seem most are Japanese online.

If in the past, attendees expressed concern about it being
boring, perhaps you can try to make it more interactive and
fun, perhaps involve the audience.  I don't know if you
format it more like a lecture or what, but throwing in a
couple of jokes can't hurt.  (^_^')

Personally i would like to have it on friday afternoon, but
i'm wondering if that would be a bad day since it's opening
day.
