from what i have read about Tech5 the core code is the same, then when it is time to compile the executable, there are "check boxes" that say build this game for:
360
ps3
pc
mac
then when the compiling is done, the core Code is the same, just the executable is set for each system. so if they did the engine RIGHT, the 360 is optimized for its cores, the ps3 for ITS spe's, etc...
