Odd poll, isn't it fairly obvious that the overwhelming majority here arn't going to be going. Its in the states, its expensive and most people have day jobs.
While I assume a large number of people won't be able to make it, I'm curious about how many plan to go.
Unfortunately you can't see the poll results without casting your vote, and if I only provided a "yes" option than only the people who voted "yes" would get to know how many people are going.
Not to mention, don't you have to be "in the industry" ?
I first attended GDC while a research scientist at NYU, so AFAICT "in the industry" is pretty loosely defined. The cost is likely to be prohibitive to a lot of people who'd have to pay for it themselves, which tends to limit it to professional game developers who's companies can afford to pay their way.
