like i said before, believe what you want.
not everything that happens in game development winds up in wikipedia or in a developer interview...
and the information i am telling you is stuff you wont find in those sources..
anyways, ask yourself the simple question how did borderlands 2 attain such a nice high quality while aliens: cm is far inferior to that standard ? the simple answer is this game has gone through the hands of many many people... many redo's, scraps, and in many ways kit-bashing their way to make something out of what is really nothing gameplay wise...
measuring exactly where bishop's blood falls in the sulaco does not equal a great game...
anyways, believe what you want
but there are very clear reasons why this game ended up why it did.. whether those become public remains to be seen.
