KORD will be a total remake from the ground up. Then KLAS and KLAX will be the next sceneries to be updated.
We confirmed to be working on both Charlotte International ( KCLT ) and Louisville ( KSDF ). Those two are being made by two separate teams, so their development is progressing in parallel, and won't affect the release of the KORD/KLAS/KLAX updates.
We are also working on an update for Geneva, which is also made by a different developer, so it's progressing in parallel too.
