When relatives and friends come over for Christmas a large group of people will be exposed to the Wii for the first time in person; they're likely to play Wii Sports and/or games like Wario Ware, Mario Party and Rayman Raving Rabids and most of these people (including non-gamers) are going to have a (really) good time. After Christmas these gamers are going to look into getting a Wii and the Wii's sales will remain fairly high in comparison to the PS3 and XBox 360, potentially even selling out; many of the Gamers who played it at Christmas may wait for different games but will (likely) be drawn to Mario Kart or Smash Bros in the first half of 2008, and many of the non-gamers will be drawn towards Wii Fit upon release.
To be fully honest, I'm not certain 1.8 Million consoles is enough to satisfy demand across the world without regional shortages
