Actually, I imagine it more like this.
Behind closed doors, Nintendo shows the Wii U and its possibilities. Right after they're done, Reggie hears one developer say to his colleague: "Man, I can't wait to tell my friends about this".
Everyone in the hall turn silent, and Reggie walks up to him, pulls up a knife point it to his face and says: "If you can't keep your little mouth shut, you and your family are in big fucking trouble". Then he makes a deep cut in the developer's hand. Everyone in the hall remains silent, and the only sound you can hear is the heartbeats of frightened video game developers.
Reggie also uses a british accent.
