In the end we had 174 names from 33 countries and 45 pieces of fanart to send to Arakawa. I also bought the following to send with the letter (actually it was more like a package.) The image is large so I am putting it behind the cut.
So this is the final update unless we hear something from Arakawa but even if we don't I still think it was a nice gesture. Plus it was really neat for me to see how diverse we are. :)
