This article seems so similar to the types of arguments we were seeing at the begining of 2007 ...
The PS3 had the best games for the year (Lair, Ratchet and Clank, Uncharted, Heavenly Sword, Metal Gear Solid, Gran Turismo and Final Fantasy), had an amazingly popular movie format (Blu-Ray) and was so powerful that everyone would buy one. The Wii was only selling well because Nintendo fanboys were buying them, and the unconventional or "casual" gamer didn't exist; and the XBox 360 only had Halo and was doomed to only sell in America.
... The problem with all of these arguments is that they don't consider how the typical gamer (read: non-"Core" gamer) actually reacts in the market. Most typical gamers will not spend $300 or more on a videogame system, will buy the games they listed but if they're only available on a system they don't own they won't buy that system (they will choose to buy a similar title on a system they do own), they may (or may not) own a HDTV but they probably didn't buy it because it was HD and probably don't have it hooked up correctly, and they play videogames because they're fun.
