No chance LOL. This is a wind up right.

Reverse engineering takes way longer than developing the game engine did for PD,
The PD game engine is their own work.
Its not the Unreal 3 engine that was ported to do car racing.
The OS on PS3 is not Windows, its a Sony Specific linux OS.
Even I know PowerPC CPU from IBM are No where near the same architecture of Intell or AMD CPU never mind the Multi different GPUs of PCs when the PS3 only has one specific GPU used.
SCE spent a long time getting SDKs for PS3 out to developers this is what PD used to build their game engine...
