You have to look at it from a business perspective, not a consumer perspective. Releasing a DLC that says game over to an already angry customer base isn't a smart idea. Which is why they didn't do it.

It´s about what quite a lot of IT supporters at that time thought or hoped would be in the announced DLC. My question was: Before the extended cut, weren´t IT people expecting that the ending DLC BW announced, to be the confirmation that the pre EC ending is an illusion?
Your answer to the guy who said, that it´s not his theory and who asked what people who were into IT were thinking, 3-4 years ago, is: It doesn´t make sense fom a business perspective.
Thanks for your input, but BW´s stance at that time was irrelvant for the question. That´s like answering the question:
"Hey Mr.Fob what ending do you prefer? You specifically, no one else."
with
Rossler: "BW said all three endings are valid and equal."
Nice to know but I still don´t know Mr.Fobs preferred ending.
That, and they've already told people numerous times that there is no canon ending. So there won't be a DLC released telling people which ending is correct.
I was talking about the expectations/hopes of some consumers for the announced ending DLC, now known as the extended cut before its release 3 years ago.
Good god.
