GT5 development took 5 years (+Polyphony delivered GT PSP and Tourist Trophy in this time)
GT6 development took 3 years (2010-2013). The game was a solid entry with lots of improvements but the upgrade wasn't that big, nevertheless it's one of my favourite GT
GT6 came out a week after PS4 launch, it didn't sell well and PD has still not given sales numbers, something they had always done. Did Yoshida really think that was a good idea, especially in Europe where racing is big?
If GT6 was worked on for an extra year or 2(giving it a similar dev time as GT5), it would've come out before christmas 2015 and PS4 would've had a great system seller to go with a price cut this holiday. In 5 years since the last game they could've made GT6 something special. PD didn't need to have GT6 ready by 2013, they were living off GT5 which was still selling a few hundred thousand copies each year, and if they needed cash a GT6 Prologue would've funded the entire GT6 development like GT5:P had done.
Now instead the cycle for a new GT has only started last year which either means waiting at least until 2016 (3year devtime) for a smaller updated GT7 or waiting even longer for a bigger updated GT7 while we could've had a GT6 with big updates this holiday.
I don't expect it to reach Driveclub in visual fidelity, and considering their reluctance to do away with the standard ps2 cars, I don't think it's going to be the revolution we are waiting for. It's going to be another incremental update.
Please don't Forza-fy the series Sony!
