How come in the latest round of previews all of the gaming journalists didn't have a problem going and doing whatever they wanted to?
Bear in mind that as release day approaches, they will allow more and more about the game to be revealed. I'm sure they planned in terms of what reviewers and trailers are allowed to show, and they may even have had planned in advance what aspects of the game would be "showable" at each of the big conventions (E3, QuakeCon, PAX, etc). It also frankly depends on how much is "done" enough to show. Given that PAX is going to be very close to release day, they may have been ready/able to show more.
From the social media I have been able to tell that Many of the Obsidian folks are now Playing (i.e. testing) the game, so we are likely very close to the final cut of content (aside from bug fixes). Plus one has to bear in mind that it's Ausir we're talking about here, and he is one of the most Known Fallout experts around. I would also not be surprised if he was under more scrutiny than other folks trying the game out, precisely because they knew whatever he saw would hit the Wiki and be seen by millions.
Either way, I suspect the PAX demos will be more free than E3 and QuakeCon in terms of what you can do - again Have Fun!

The rest of us will have to wait for October 19th - but I took vacation days from the 19th-23rd that week, my first-ever vacation taken on behalf of the release of a video game. Clearly I have been assimilated. :fallout:
T-Minus 54 days to V-Day.
