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.
Well, It's not conventional :-/ It would need a big runway!
Either way, we'll see how the Boeing pelican does...
