I don't know what the value is in having people go back and forth about what show is better. Robin made his decision, and so the focus should be on that part of the event, not whatever other complaints or suggestions about the show.
The last three times I've been to Expo (I know I missed last year), I can count the number of games I played on one hand total. I could care less if there were 2 games there or 2500, it's less about that for me and more about seeing and talking with people who share a common bond.
Expo offers some unique things, and if seeing Robin in person doesn't convince you that it is a show you want to attend, check out the web site, see if the different things that are there are up your alley, and if so go. If not, you can look at other show web sites, and determine which one best suits your tastes. Or, maybe shows aren't your thing, and then you just don't need to go. No one is forcing you.
I always personally wish that Expo fell a couple weeks later, as it is always at the most impossible time of the year for me to go, but I've managed to make it down there something like 11 times in the past 14 years.
