There's no update price
with any of FSDT'S sceneries.

Normally yes, but for the KORD update, we are considering two options:
1) A "small" update, that will just update runways to the current status, without adding anything extra. This will be surely free.
2) A "large" update, which will set KORD to KDFW quality standards, which means whole ground remade fully 3d (with elevated taxiways), using Shaders, custom lights, special THL, FAROS, RHL lights as in KDFW, in addition to be updated. This will be a new product, that will be offered with a significant discount to existing users, I think everyone can understand how big the workload involved is, it would be similar to redoing from scratch about half of the scenery.
Both options have their merit, and we are not entirely sure which one would be the best, and the issue is, it depends also on our future projects and how we can allocate our limited resources.
