It doesn't really matter if I go or not, as all the sites over the net will be filled with MGS3 video. Damn.........that would be just amazing.
I still remember the day when I first time ever downloaded the video for Metal Gear Solid 2 back in the Summer of 2000. I was acting all crazy for atleast 2 week. The first time I saw the Pic of Solid Snake from MGS2 was from GamesRaidar site as far as I can remember.
I am also looking forward how more can they improve the game when it comes to GRAPHICS, thats a tough one to beat! 
BTW, Kojima has stated he'll direct MGS3. In the current issue of XBN (Xbox Nation) on page 114:
"I want to be very innovative and try to throw in a lot of new elements in the gamplay. MGS3 is very high-tech, and I'll be directing it myself."
This interview is from the Tokyo Game Show though.
There you go, when will Kojima be truthful to us ever!!
