So far the one aspect of upgrades on 380 that hasn't been discussed and is the most important one: politics.
If TC doesn't want it, then AR, TCAS and the rest of the puppets don't dear to say anything. Although the course is ready, its not approved yet, and will not be for a long time. Also some of the golden oldies of the the 380 don't like the idea, cz then they don't feel special anymore.
Same happened to the Ipad, shafted due politics. Civil servants and bureaucracy, lack of industrial revolution.
