I really wouldn't put too much stock in the videos. I think they were simply an attempt to get people hyped up for the press conference. For those that didn't see, there were four videos. The starting video was apparently random, since I got Reggie first. Once you got through all four clips, you looped through again in the same order. I have a 56k connection, so two of the videos didn't work so hot for me, but based on what I saw:
Reggie Clip: A very short clip. Reggie appears and basically says, "Don't make me do it. I'll take your name." Rather amusing.
Female Clip: There's a female Nintendo employee at a conference table (not Perrin Kaplan, Bill. Do you even know what Perrin looks like? Perrin is a brunette, close to middle-age lady who looks decent for her age. The woman in the clip was young, had short blonde hair, and was quite frankly pretty hot

) Anyway, she's going through an itinerary - "We have the launch party on Tuesday, the website up on Wedensday, going to a presentation on Thursday - I'm looking forward to it - and on Friday" At this point, the woman looks directly into the camera and says, "Guys, we are so busy. Can you come back later . . ." And my connection went out from there, although I think there was a bit more.
Face Clip: Basically concentrates on two eyes that look shiftily around. I couldn't get to the end of the clip, so I don't know whether they panned down and showed the face frowning.
Male Clip: I have no idea about this one, since it didn't work for me at all. There's a guy at a conference table, and he's jibber-jabbering about the E3 presentation, but the connection here was so static-y that I really couldn't make out anything.
Just hype for the conference presentation. Those who are putting undue attention on Thursday (and I have no idea why the focus is on Thursday in the first place, if anything, based on the clip it should be on Friday) are simply concentrating on one small facet of the videos to the detriment of the whole picture.
