有人去问微软，微软说Forza6会是1080P+60fps
另外有人整理Forza4~6发售首日的车辆收录数与场地收录数

Forza 6(Day One)
450+ cars (+217+ cars)
26 environments (+12 environments)
Forza 5(Day One)
233 cars (-300 cars)
14 environments (-10 environments)
Forza 4(Day One)
533 cars
24 environments
Forza4是360末期才累积到这个数量，现在Forza6在X1推出第二年就快达到4代的
收录量了!
