Yep Gran Turismo has become smaller in NA and EU however it keeps on growing in EU. However it has been a long long long time since the last flagship GT game released and a lot could have changed in that time.
My guess is that GT5 will do 1.0 million LTD in Japan and at least 4 million in EU. These PS3 Slim rumours are getting pretty serious now so my guess is that Sony will release the slim with GT5 = system seller.
It must be noted that Prologue has reached something like 0.4 million without bundles and the bundles stopped pretty quickly so it should de a million.
