Given that 2024-native aircraft need an significant 3D model rebuild to deal with the modular LOD, etc. it’s not just a matter of “let’s spend a few days bringing the flight model over to the new 2024 version.”
And given this thing has custom instrumentation, I’m guessing native 2024’s going to take some real work.
That said, once 2024 is out, I’m not going to be buying new 2020 SDK aircraft even if they are 2024-compatible, so I’ll anxiously await the 2024 version of the Starship!
