My understanding of the PSX hype was that people were enjoying themselves but no one actually believed most of that stuff would happen. I mean, if you did...
This is usually how it goes. People 2 weeks ago barely cared about E3. Then they started posting jokes about TLG, just because that's what you do this time of year, and then the very fact that it's being mentioned feeds into the actual discussion on the game, which in turn feeds into the thread's energy, until it builds into actual hype, generated from nothing past the fact that we're posting. It's the inevitable E3 tradition.
