Some other possible factors for high PS4 demand:
1.People are more accustomed and comfortable with spending money on tech after smartphone/tablet explosion, in fact the next gen consoles look a bargain in comparison to the latest iPad or Galaxy S4 for example.
2.Very long wait since start of last generation. 8 years is a long time to be with the same hardware. More people ready to upgrade.
3. PS4 looks better than X1. Aesthetics do mean alot for many people, even for a living room/bedroom box that might be hidden away. Where X1 looks generic, PS4 is more iconic and, possibly, desirable.
4.Price. $100/£80 is a substantial differentiator. Also cheaper than last generation's starting prices.
5.Latent PS brand love re-emerging from PS2 era. In my opinion, PS4 looks more welcoming and warm with its medium blue colour atm, while Xbox's radioactive green might even be enough to offput some people.
Ok, so some of the points are clearly small, subtle factors, but they all add up...
