This cool video (about 3 minutes) is from Boeing's sales department showing some really great things that airlines can do with the new 747-800 interior. I really like the business lounge and exercise room. And I like all the internet terminals everywhere.
But we all know what will REALLY happen: the airlines will rip everything out and squeeze in as many seats as humanly - or inhumanly - possible. The flying experience is getting worse, not better.
