Microsoft and Asobo informed that MSFS 2024 will be fully compatible with the SimConnect interface made for MSFS 2020. If that is true, current SkyElite should be compatible with MSFS 2024.
So the plans so far are to wait to see how this is going to behave. If their statement is true and current SkyElite works in MSFS 2024, there is no reason to plan anything yet.
One way or the other, if there is any reason to develop a new version for MSFS 2024, we are not going to jump into this immediately, until we see that MSFS 2024 is somehow stable.
