Not sure if this will mean much to the non-believers, but:

We were inundated with tips this week about supposed "proof" that code found within Mass Effect 2 on PC "confirmed" the presence of a PS3 version of the game. It does not.
Seeking to clarify the situation, a statement on BioWare's forums reads:
The Unreal Engine is cross platform, hence the PS3 code. This was brought up back in Mass Effect 1 days as well.
Mass Effect is for the PC and Xbox 360.
LOCKDOWN!
Lockdown indeed. If you check the code for other Unreal Engine games - like Gears of War - you'll find the same thing.
Nothing to see here, people.
