Let me try to simplify the second to last message:
How many people do you think would buy something like Action Comics #878 based on hype that said "This story takes place out of continuity", and how many people do you think would buy a one shot called "Superman: This Story is Out of Continuity (ok, the title sucks, but you know what I mean)?
Historically speaking, in continuity stories sell more than one shots do, while out of continuity stories told in the main titles have, for the past five years, killed the Superman franchise.
Look at all the attention that Rucka's run has gathered even before the first issue came out, all based on rumors that said that he's using the John Byrne MoS continuity.
That doesn't tell you anything about what readers want?
