Forza is funded by one of the richest companies on the planet, who can hire 400 employees and design companies across the globe without batting an eye, pay the Porsche/EA licensing fee, and hire a Hollywood graphics company to help create their graphics engine for Forza 4. You know, Hollywood, the one place which can rival Washington DC with how large sums of money get spent instantly.
Things have been "dire" since the days before the launch of GT5 Prologue, and PD just keeps chugging, producing the most popular and prosperous racing game in history. Every year, people bail on the series swearing never to return, declarations of doom are made, and they always come just as true as every environmental prediction. I can't see this year being any different.
