The Xbox 360 Slim, or Xbox 360 S if you prefer, was announced by Microsoft during their E3 press conference. Most of the reception so far has been pretty positive too, but it doesn't seem to be the case in Japan.
The new Xbox 360 S has just been put up on Amazon, and so far it's only received 1-star ratings from consumers. At the time of writing, no other score aside from 1 had been given, which really shows what Japanese gamers initially think about the Xbox 360 and the new Xbox 360 S.
Perhaps their opinion will change over time.
