Quoted from SpookyCharlie:

I'm not in the habit of bashing anyone, so going to try NOT to start now.
Bottom line is we spent a full 2 days working with a partner company that supports us, is as kind as it gets, had a doors wide open day Thursday, and Friday decided to make their event about raising funds for a great children's charity in the Juvenile Diabetes Research Foundation. We sold some games, met a ton of people, and had a great time.
We wish Mike and everyone at Expo well. It's their show, they will do as they please. If they are happy with the state of what it is, then that's all that matters.
We'll be taking TnA to as many shows as possible in the next year. Come talk to us and play a few games... we kinda live for this stuff.
