2. The second point is that somehow in your analisys gamers have amensia and that the previous brands for Playstation and Xbox don't count for nothing in todays marketplace. "360 isn't competing against it's numbers from 5 years ago, it's directly competing with the PS3's sales" If the Xbox brand had not been estalished for which the X360 to stand on then the conversation would be null. The same for the PS3 and thus far their numbers are looking good against the PS2.
Branding isn't enough to get people to buy a $600 gaming console in the kinds of numbers as the PS2. The PS2 was "only" $300.
