I know they're smaller than say, NY or SD, but what kind of things can you expect to see at these two?

I plan to go to one (Hopefully both:D) but if it there isn't really anything I know of, there isn't much point going.

That probably sounds really close minded, but I'd want to go to see Star Wars or Halo or something.

Learned of one happening next month in Austin...

Never been to one but expect some dudes selling photos and autographs... some dressed up as Sailor Moon

Along with people hawking anime and comic merchandise.

I tried to go to the NY one last year but the tickets were sold out. Eventually I'd love to make it to one. I've not been to one over seas but they are probably similar to the US ones albeit smaller. Probably see a lot of people dressed up and vendors and what not.
