It's already out.
yes thats why its on the cover and it was shown at the demo
There are no nitros in Forza 3.
yes
No. Forza 3 is an Xbox 360 Exclusive, and rather than Forza 3 on the PS3 there is Gran Turismo series. the chance Forza will come out to the PS3 is very very VERY Slim.
Forza Motorsport 3 was released October 27 2009 for the Xbox 360 and Forza Motorsport 4 will be released in 2011
Forza Horizon is a Xbox 360 exclusive.
Need for Speed Shift and Forza Motorsport 3 both deal with racing simulation. Need for Speed Shift deals with more of the driving experience and did a verry good job of doing it. Only the actual driving is more unrealistic. You'll be going a heck lot faster than in Forza. Forza 3 is more on driving in general. You'll be driving fast on straitaways and slow on corners. But the cockpit view is really boring. Both games are good, but I suggest getting the demo versions of theese game before making your desitions...
There are about 400 cars in forza but you can get a extra 90 by dlc
More cars and tracks probably
There used to be a glitch to do this but it has now been fixed. There is no way to get unlimited money in Forza 3.
