Well it's been revealed for PS3 (to the discontent of some) and coming this holiday. GT5 was adjusted to over 10m recently but it came in the middle of PS3's life cycle. How will GT6 do at the end of PS3's life but on a larger install base? Will its legs be cut off prematurely? Will it skyrocket as the first "true" GT game on PS3 (as some say GT5 was disappointing)? Speculate!
PS: Let's just talk PS3 version here
As for me I see it selling about 9m lifetime. GT2 sold about 1.5m less than GT on PS1 and the numbers for GT are very similar to GT5. That's not all there is to it as GT4 sold about 3.5m less than GT3. I think the time in the lifecycle is part of this pattern and GT6 will follow suit. I think it will probably make more money with a bigger debut and less later sales (bigger install base to buy right away instead of when they get the system) but it won't have the same legs because by the time it gets to where GT5 is now PS4 will be big and people won't be buying as many new PS3 games.
