Nope.
Yes it has......

"The game was first revealed at E3 2006 under the name Vision Gran Turismo.
In an April 2008 interview, game creator Kazunori Yamauchi revealed that 150 people had worked on Gran Turismo 5 for four years, with all of Polyphony Digital's 120 employees working on GT5, and the game costing 50 times more to develop than 1997's Gran Turismo."
Hmmm.... 2008 - 4yrs = 2004. That's black and white. By the time the EU release rolls up it will be over 6 yrs, disregarding when or what has been released in that time since. GT5 has been in development for 6yrs, conceptualized for possibly 8yrs +........
It's been in gestation for a hell of a lot longer than 2.5 - 3 yrs.
Look i'm not concerned when it's gonna be released now, i'm tired of riding the rollercoaster of innuendo and smoke & mirrors from PD and Sony.
That is just playing it safe and reading the context word by word. If we look at reality, that doesn't conclude that they've been working on GT5 100% since 2004. It saddens me to keep seeing this, over and over again. Like I keep saying, PD is no beginner. There is a reason why there are Two FMs before a GT5, and that's mainly because the FM series have
zero side-projects. Added to that, Turn 10 have outside resource to help with modeling.
If you look at FM2, really, it doesn't compare to GT5 so technically that doesn't count. Kaz obviously didn't want to release a game that fast because we could obviously see the difference in quality between FM2 and FM3. Fm3 makes FM2 like a rushed product because the visuals were so better, it didn't even look like it came from turn 10, and we know PD doesn't rush theirs. FM3 is a lot better game to compare to GT5 so if we really want to compare development time fairly, it's about 4 years for Turn 10 to maximize (or nearly) the XBOX 360, as for PD, probably 4.5-5 years, to reach the goal they want to achieve for GT5. The rest according to them, is waiting on Marketing strategies.
About a year in gap between the two seem very reasonable, considering the fact that they're modeling over 950! cars compared to 400, and Turn 10 not having to worry about MS making them develop a portable version out of FM, nor did they have to work on a motorcyle game. PD also even had little side-projects to work on, like GTR's special HUD and collaborations with Citroen. Taken, this probably affected little, but it did take a bit of PD's employee's time out of GT5 development. Then there's other little things like working on different physics for WRC rally racing or nascar (license) races, study on electric and kers, all in which Turn 10 don't have to worry about. I can bet that if PD didn't have to worry about WRC, Nascar licenses, or any of those, GT5 production would be at least a little faster so to say it affected zero or nada, is not right.
This is looking at reality, not just through numbers and sentences.
