I'm not saying it a bad guy... I just saying it says bullshit because PD not spended 6 years in GT5... the time to developer GT5 after GT5:P was 3 years at maximum... an staff of 110 guys working in GT5 and GT PSP togheter in 2-3 year is something impressive.
And if next Xbox released in 2013 Forza 4 won't sell 4 million... 3 million is possible but not probable... GT5 will end up a little over 11 million tracking ahead GT4 like it is now.
GT5 was actually in development for over 5 Years. Here. Words from Kaz himself. http://uk.ps3.ign.com/articles/113/1132522p1.html
"It took 2,000 days to get all the ideas that went into GT5. It's just too early to be talking about GT6." 2000 days is like 5 and a half Years.
Sure, they were also working on other things, but they were working on GT5 constantly from 2004/2005 at the same time.
Also, Forza 4 will have sold 4 Million by the time 2012 is over. Microsoft will bundle it. A lot. They do it with Forza. A lot. It's a great bundle to have in Europe, because Europe loves racing.
