Cx does nothing better than make money. They know their business model and follow it well. If they buy the 380 it will be because they get it for free...the TRUE value of a Bus.... But I doubt CX will go down route again. The 747-8i is a happy medium....offers seats when needed but no over capacity during the downturns. Cargo space, reliability and commonality for crews, engineering etc...
But, ultimately, we shall wait and see! Both aircraft have their merits.
