Steve Weibe is currently (as of 6:32 EST) still going for the highest score ever on Donkey Kong at E3, and you can watch his progress LIVE at this link (if you catch this message in time):
(P.S. Just before I was about to post this, I checked the video feed again, and it appears that there was a power outage during his attempt!!!! The video feed is out, but there is still audio, but it sounds like something went wrong. Possible sabotage of his game???)
That's pretty neat how they have it set up with the twitter comments and all. Sucks they couldn't keep the power going, though. I guess it's to be expected, though. No telling what all kinds of weird stuff is attached to their grid.
