would be nice if they could at least reply.
There wasn't any reply because that O'Hare would have been kept updated along the years of the planned airport evolution, was discussed and answered many times in the past.
We'll likely have an update, but we don't have any planned release date right now, and not decided if it will be free or not, because it depends if we'll also so a remake with new graphic methods and DX10 compatibility, like in JFK V2.
Nothing is decided right now, nothing is announced. Nothing will be announced before it's decided, and it won't be anytime soon anyway, because there's KIAH to be released first, and KLAS needs an update too.
