Alan, my friend, if an airline honestly would fit-out their A380 in the config that Airbus shows in their marketing mock-up, I'd fly it in a heartbeat.
But have you seen Upper Class on a Virgin A340? It looks like a row of cubicles on either side of the aisle. Now expand that to four sets on an A380, and it'll look like a 1990's "cube farm". I can't wait for the FA to drop a set of dishes and 200 Business Class passengers "prairie dog".
I did like the Payloads Manager noting that "yeah, all those things like showers and stuff are nice, but those were created by marketers, not engineers. We'll have showers, but they won't look like a bathroom at the Four Seasons".
