That's totally a misleading screenshot though. It implies that the game was built for 4:3 and modified for widescreen, which almost certainly isn't the case.
Have you looked at a 16:9 screenshot or the actual graphics in person with this configuration? Have you looked at a 4:3 screenshot or the actual graphics in person with this configuration? Do you think they would be chopping out the arm in 16:9 if this was what they designed the game for?
There is no need to theorize on what is "almost certainly isn't the case". Just look at the facts that are available or test it for yourself and give people some evidence, not what you personally feel they couldn't possibly have done (based on NOTHING). Seriously, stop with the crap. It just makes lurkers like me register to say how fed up we are with reading made up junk in the middle of real tangible evidence.
Not one of the people who have challenged these screenshots have offered their own to back up their opinion, here or in the 2k forums. That should tell you something right there.
