some of us even buying the outdated version in expectation of YOUR word that work would start after KMEM release!
The word is still valid: "work would start after KMEM release" only means that it would not start *before*, not that it would have been the FIRST in line to be updated. We always said that BOTH KORD and KLAS are the one that will be updated next and, IMOH, KORD missing a whole runway is FAR more pressing of the new terminal at KLAS.
From an aeronautical point of view, KLAS is still perfectly usable as it is now (no runway changes), while KORD is outdated and doesn't match current charts and procedures anymore, which will cause way more issue to users, and I'm sure many bought KORD too, following our promise to have it updated.
It's just that we simply cannot do the two at once, and KORD is more in need of an update.
