Setting does not match a conference room where an actual conference would take place: placement of counter, PC on the side, lighting conditions, and obvious slope deduced from the elevation and distance of the video-taker indicates that this is in a college-style lecture hall. It's worth noting that the lights in the room are yellow-hued ("warm") while actual conference centers tend to emphasize "warm" lighting more. (excepting general-purpose ballrooms, and this very obviously isn't a ballroom)
Also, the uploader said "video game editor" in the title frame, but later refers to them as a developer in the description. The lack of audio is most conspicuous as well. All told, it's either a class, or a student-organization meeting or other similar school-related event about discussing rumors. I don't think I need to repeat all the numbers I'd worked out (and others seem to have taken note of over the past months) in terms of the controller size and the screen...
[citation][nom]eklipz330[/nom]don't be so sure buddy. that mockup design has been everywhere, and it is probably going to be it. besides, videos like these are often released before time, so it's not unusuali understand where you're coming from, but remember this: engadget's mockup of the XPERIA PLAY was in fact, VERY CLOSE to how the phone really looked. they may have actually seen it before hand[/citation]
And remember this: Nintendo gives out very, very little information. (case-in-point: while everyone repeats IGN's faked numbers on clock speed, does anyone know how many TMU's the Wii's GPU has?) Similarly, IGN had been at the forefront before E3 2006 (or was it 2005?) in declaring that the controller for it would be a giant touchscreen with no buttons. We saw how THAT turned out...
