Point taken, but the other questions still remain. There are only 3 solid competitors in videogames, and it\'s a billion-dollar industry. What other market are there only 3 choices?
Growth of gaming in 2007 far outpaces movies, music
There are plenty of competitors if you look at the software developers and publishers. You\'re talking about proprietary hardware which is different.
That\'s like how there were three competing DVD machines and we couldn\'t support that so all HD-DVD players became obsolete.
Three is not a small number in this case.
To allow for more competitors, you\'d have to let other companies create consoles that could play Nintendo Wii games or Xbox 360 games, then count those as competing companies, too.
