We haven't really gotten an actual source on that. Perhaps if the article said something like "So we traveled to the Bethesda HQ in Maryland for a special playtesting of the first 30 minutes of the game" then I would hop aboard, but I'll wait till I find the article.
For anyone interested, Gamestop owns the Gameinformer publication and you can go to your nearest Gamestop and buy one, if you have one in town.
