I'm going to read them when they're released; I just can't help myself. I'm such a DUNE geek.
My cynicism sense is tingling though - so they couldn't fit the story into one 'triumphant conclusion', they had to go for two more books. It's because the story is going to be so good that they couldn't bear to leave anything out, not anything to do with making more money at all, right? Right?
Please, at least get them a decent editor. Anything that will improve their prose.
