A day later and still looks like no real interest from the fandom over this. I guess if you are travelling a long way and spending thousands, a $500 VIP tour of one of the current creative houses of Transformers wouldn't seem so bad... but to the locals, it's too excessive.
It would be funny if there only ended up being one or two people going... but I think by the time the convention week starts, others will sign up while they are in San Diego. (there's no cut-off date)
