Without going into great detail, lets just say this is a trade show, not fort knox. They're not going to do a background check on you, and the actual requirements are pretty easy to get past. It's pretty damn easy to qualify as press/media.
I went in 2006, and most people I was going with were preregistered, but I didnt get mine in on time. There was a long list of stuff you needed, a business card, a printout of an article you've written etc. I was a bit worried about getting on the plane without having my shit in order beforehand, but at the actual registration booth, the clerk was shocked at how well prepared I was. If you do everything to the letter, you'll get in. Even if you mess up a bit, they'll more than likely let you in, since you are paying for the privilege.
One look at the crowd before the doors opened, which was 90% sweaty fanboys, and you knew the vast majority of people there didnt really "belong" there. The point is, if you really want to go, there's very little standing in your way, but it isnt as easy as just buying a ticket. You'll have to be...creative.
The best part about getting a press pass is the press kits you can request from the reps. Those things sold for $$$ on ebay...a few squaresoft ones practically financed our entire trip.
