Aside from the ridiculous comment that the US is the least charitable nation, for your information it gives the most. Ill focus on your gaming statements.
The us is beast of a consumer and not only that are by far the least prejudice with their consuming dollars. Which does mean that the us consumer can easily switch over to the ps4 next gen, however this doesn't appear to be the case.
First, the Xbo and the ps4 will go on sale same date your assumption to the contrary is simply not supported.
Second, the us market continues to prefer the the Xbox over the ps3 despite your claim that hardcore gamers are in lock with the Sony brand, this cement is again simply far, In the is the hard core gamer is evenly split with a advantage to ms.
Third, the brand appeal of ms is quite high in the us and the uk for that matter, and it shows no sign of falling apart.
I think Sony will do better than this generation in the us and the uk but I think ms will still win the sales war.
