well, no. Dune 7 wouldn't have been about The Butlerian Jihad etc....but those stories, as written by KJA/BH, are "wrapped around" elements of Dune7. KJA's earlier response to the Baron makes that clear. So as you read the prequels, you are "set up for" Dune7. But another way of looking at it is that you are receiving bits and pieces of Dune7 the whole way. Another thread would be: what would FH's version of the BJ been like, were it to come after his own Dune7? It just makes very little sense to me that KJA and BH feel the need to "set up" Dune 7 with the BJ when FH would have written the two in the opposite order. Clearly FH needed no such setup. I think KJA/BH must underestimate the Classic Dune Audience, or having longer lifespans they have decided to just stretch things out a bit. Like KJA implies in his email to me, Dune7 proper could be more than one book. I say it is already more than one book! But what do I know, I am just a sand flea :-) :-)
