The Wii was the focal point of E3 2006 as Nintendo proved it was on the cusp of dominating all of gaming.
The state of Nintendo before E3 2006 was that of a company on the rise. By this point, the DS was an unabashed success, crushing the PSP and dominating the world with Brain Age and Nintendogs. Their next home console (Wii), known as the Revolution up until a few weeks before their E3 show, was due out at the end of 2006. Things were looking good and the ensuing E3 presentation reflected that.
