Trojan Rabbit, the second point you made is the most far-fetched thing I have ever heard. The market DOES want jumbos - the bigger (A380) the more people it can carry in one flight, and the faster the money rolls in. They don't want a crappy little Dreamliner taking only a few hundred people across nations at one time - more flights would then have to be made, meaning they will LOSE money (more flights = pilots with higher paychecks).
Also, the Antonov An-325, would not be a jumbo. It would be a CARGO carrier, and the market would love that, as it means they can carry more cargo in one flight.
In the end...your logic simply does not work.
Actually, you can't compare the A380 to the 787, each are in a different market and have different uses. the A380 is designed for long distance, high capacity flights, e.g. Syd - Lon. The 787 is more or less a replacement for the 767 and competitor to the A330. It is designed for slightly shorter international routes at a more economical price. Used correctly the 787 will be cheaper than the A380 on certain trips.
