As for the topic at hand, I don’t really know what to think. Going all out open-world like Skyrim or whatnot doesn’t seem very appealing. It feels like it’d just detract from the story and lose focus, considering the huge change in style. However, going in a less extreme direction, similar to Crysis or such could be interesting, simply making it less corridor-y.
I highly doubt the information is real in the first place, though.
