Hi with the tristar and a340 having passenger cabins on Xbox, is the a380 gonna have a cabin on Xbox too?

That is the plan yes, but we can't say for certain until final testing on the platform of release candidate. The A380 is still in active development currently.
Expect more information closer to release :)

Thanks for replying hopefully it’s possible. Just wondering could you do something like two versions of the aircraft one with a cabin and one with out that you could select before loading in to the sim
