I would say that for a lot of people the default brand is still Playstation. The performance of the PS3 seems to be a strong indicator of this. It seems to me a lot of people who enter into the store have that one brand in mind and the difference in price is the only thing causing a lot of people to even consider the Xbox 360. Theres also the factor that a lot of the killer apps for the 360 are much stronger in the U.S. than in Europe which doesn't help.
The fact that the Xbox 360 is cheaper than the PS3 doesn't help all the time. Quite a lot of the time people will get what they want, rather than what is cheaper. They will buy Coke because its familiar even though they know that generic cola for half the price tastes the same to them. If the roles were reversed and the Xbox 360 was called 'Playstation 3' is there any doubt that the console would have performed significantly better? Afterall the PS1/PS2 sold 200M between them.
Tease.
