Did you see the FB invite via NSXoTX? 9 going and 10 maybe so far. https://www.facebook.com/events/283327501998261/ The weather looks to be nice so I bet it will be a great turnout. FYI when the weather is nice you need to be on time to grab a spot in the show lot. If you don't care to show your car then park on side street and walk over whenever.
This meet attracts real exotics so its usually pretty good.
I've been to the one in Dallas a few times, maybe once this year. The atmosphere of alot of the other exotic car owners is somewhat offputting. Probably 9 of us went late last year, but it's usually onesies or twosies at most. Having to get up at 6am just to get in is kind of early.
