As far as comparing sales to GT4. Remember that GT4 was released when PS2 had over 100 million user instal base.
PS3 is around 40mil now so if GT5 sells in a longer amount of time, there is a reason.

When GT4 was released I had bought 3 PS2 and no other console. This time I owned one of each Ps3,X360 and Wii. So 100 milion sales doesn't really mean 100 million user base.  How many PS3 owners own more than one PS this generation? I willing to bet their more gamers like me who bought 2-3 different consoles instead 2-3 of the same last generation.
