Now I don't know if this has been posted yet, but apparently Forbes got into touch with "someone" close to From, and was able to shine some light on the issue.

Some choice quotes from the article:
This is what it comes down to: a playable framerate. The early builds that the screenshots came from were playable but only just so. The game was not in a state where it could be sold at that point. I strongly suspect that they were focusing heavily on delivering a top-notch experience on PC and underestimated the challenges the new systems would pose on PS3 / Xbox360. Thats my analysis, anyway. But, factually, the early builds played like Blighttown the entire game.
I sincerely dont think they intended to deceive, but in the end they sacrificed a huge amount of graphical fidelity at the very end of development because they couldnt resolve the framerate in any other way. They had to promote the game with screens and trailers, but at that time even they had no idea they were going to have to drop the settings so much, I suspect.
I want people to know the truth. I know a lot of people just feel lied to, but I think the reality is a bit different. It doesnt mean they handled it properly, but I think they made the only decision they COULD make in the end. The game would have been much worse without the change (as in, many would call it unplayable and broken.)
Sounds like From bit off way more than they could chew (god knows the praise for their games is not for the technical aspect). But still, the way this guy put it, it sounds like they had it running on a PC on one point, which means that something must really be up if we don't get the improved lighting with the port.
