Seems to me that if AP didn't come to Expo people would be critical of their lack of public presence and accuse them of hiding behind an elaborate scam. Now that they are wanting to come to Expo people are critical that they have the floor to present themselves in what could be an elaborate scam. Damned if you do...damned if you dont.
If having to choose between the two I would rather they come to Expo so those that may want to have a face to face have the opportunity to do so. I personally would like to see with my own eyes and hear with my own ears before passing immediate judgement on intentions of AP.
