forza 2 was bundled like crazy
the first did 2,5 million in us lifetime and forza 3 doesnt even have more than 100k preorders in us
for comparsion:
uncharted had 1 million in us lifetime and the second has 250k preorders as of now
Forza 2 even got outsold by GT5:P
despite F2 (as said above) was bundled like crazy in 2007
F3 wont even make 3 million
