From NPD and GFK we know it did 200-225know in US+UK. Since racing games tends to do better outside the US than in it, I think this is a reasonable estimate.
FH3 did very well. Without massive bundling Forza games tends to sell 2-2.5 million copies FH3 will have no trouble passing this number.

This sort of game will sell well digitally. Your looking at over 50 hours of launch content plus dozens of others with dlc. It should have problems selling well. A smart summer/spring bundle will help it get 2 million or so.

Seems like an improvement in sales.

I hope no one says it sold horribly because attach ratio compared tô fm5 or fh2 is a lot lower. Since we all recently discovered sales increase almost 1:1 with userbase.

And on the comparison with nms being unfair because of nms genre being more popular. when have indies became more popular than racers on individual titles? or which is the genre of nms? on the racing being declined as franchise I'll want for gt te decide, because driveclub have done good enough for a New franchise. so the decline of forza May have more to do with the profile of xbox owners. 

This.. digital sales are more appealing now with play anywhere. Digital rights are also beneficial for fatties so they don't need to waste calories getting up.
