We already updated KORD V2 SEVERAL TIMES, for FREE.
But it's just wrong to assume a scenery could be constantly updated to real charts and, in this case, the changes after the latest update are not just a couple of taxiways, but a whole new part of a Terminal, so it's not a quick work.
I should remind you, to get updated charts in realtime, you surely pay a subscription, that's not how sceneries are normally sold, and I don't think many users would accept that so, you just have to realize, a scenery cannot be updated with the same frequency of the real world charts ESPECIALLY when it's a one-time purchase with no monthly fees.
