Apparently, cutting a console which is $400 to $300 is causing people to think it will increase sales. I have to say that I am one of those people, 360 could come with a happy after the PS3 price cut however fact of the matter is that people would be more likely to bite the bullet and go for a PS3.
Gamecube was $99 and the PS3 is said to be the GC of this generation at $400, by the time the PS3 is that price I will be shocked if it has not done 50 million. The PS3 has so many first party, second party titles as well as multi-plat games, I'm sure there is a game on that console which will cause people to purchase it over the PS3.
Price cut this generation causes a larger spike in sales compared to games, FACT.
