ICheck out this article series from Chuck Rozanski and his experience at San Diego Comic Con. You may have to flip around on the site and choose the dates at the end of July pertaining to the convention to get the whole gist, but it is worth the read. He is a man after our own hearts who had a rather sad experience after going to the convention for about forty years. I think there is a case for missing what was good about conventions and collectors of the past who weren't out for profit but for the love of comic books. Could be a wake up call to a sad state of affairs to come for this fragile and still under appreciated medium.
