Hopefully at least a few reviewers will get a chance to tinker with it and give the rest of us an idea of how the game is feeling so far. With the release date only a few months away, it should be a fairly accurate picture.
They'll also be hosting a public demo and other content, all in an attempt to generate more interest and hype on the game. The title has a lot to live up to, but so far Bethesda has responded warmly to the existing fan base. This includes working to remain true to the Fallout nature, which sometimes includes controversial content. I am certainly looking forward to release day.
