I'm sorry, but this is a non-issue.
The 380 is a big transport operating about 0.8M, the cruiser is a smaller transport operating about 0.95M. They are aiming at different markets, both of which are healthy(ish).
Nobody is going to buy a cruiser for a major low-cost high utilisation tourist route. Nobody is likely to buy an A380 for an executive route between two major financial centres.
