I've spoken to people who are only buying a next gen console for GTAIV, and are buying a PS3 because they "don't trust anyone but sony to bring out GTA". I've told them about the 360 exclusive content... they doubt it's true. It's incredible, the level of fanboyism to be found amongst people who aren't even that keen on computer games.
Sony tapped into a market with playstation that went beyond the typical gamer. It still thinks PS is cool, and other computer games are nerdy. With the wii, nintendo's gone totally beyond this demographic, but they're the people microsoft and sony will be fighting over, and the PS brand is still massively important to a lot of them.
Other than brand loyalty, why have nearly as many people bought a PS3 last year as bought a 360? We're seeing the impact of it in front of us, and still, people deny it.
