No matter what Brian Ashcraft of Kotaku says, there is a curse of the third video game console all the way back to the Atari 7200. Each manufacturer's third console has resulted in major loss of market share or eventually led to the complete collapse of the company.
Atari 7200- last ditch effort to save Atari failed, company sputters around somehow for 20 plus years as a software company, minus two failed hardware releases (Jaguar and Lynx) after being acquired several times before finally going bankrupt last year.
Sega Saturn- Worst launch in the history of games causes third parties and some retailers to abandon Sega and even a great Dreamcast launch can't save them and they have to abandon hardware to become software only to survive.
Nintendo 64- Hubris of Nintendo causes Sony to make their own console and beat Nintendo at their own game. Now faced with a strong competitor to Nintendo, third parties flock to Sony for its cheaper disc-based infrastructure even though the system is harder to develop for. Outside of wrestling games from THQ, the only hit games on the N64 were either first or second party titles and in a world before having two consoles was a common occurence, Nintendo falls to 2nd. That eventually becomes third place after Microsoft's XBox console launches on the strength of Halo, and Nintendo's Gamecube can only counter with Super Smash Brothers. Also the Black Gamecube becomes hard to find for the first year as teenagers/young adults don't want "a purple lunchbox" under their TV.
Playstation 3- $599 US Dollars, "get a 2nd job," crying baby ads, no games, no achievements, etc.
Now Nintendo recovered with their 4th console but their 5th seems to be on a worse trend than the Gamecube. PS3 recovered to equal XBox across the world and take over the lead in Japan and Europe, but in North America, it's a distant rival to 360. Going with the current rumors, that may be about to change.
