I was just listening to the new episode, and had some thoughts about the Darth Plagueis discussions.
Re: Palpatine's name: There's a great meme online (I think on TheForce.net, mostly), that Palpatine's name is Frank. Just because in Episode I he says something like "Your highness, let me be frank." Love it.
Re: Plagueis making Anakin: I really hope they don't have Plagueis create Anakin. If only because, according to previous sources (like The New Essential Chronology), Plagueis died 5 years before Anakin was born. And I wouldn't like if they retconned Plagueis's death to being the same year as Anakin's birth, if only because that would reduce the duration of Sidious's Mastership and Maul's apprenticeship under him.
Re: Maul on the back cover: I assume the book would end with Sidious becoming the Master and taking Maul as his apprentice, just like how Darth Bane: Dynasty of Evil ended with Zannah becoming Master, with Cognus as her apprentice.
Thinking of Zannah and Cognus, I really really hope that the Plagueis book doesn't end with unintentional ambiguity. I still chuckle when some people on the TFN forums argue that Bane survived in Zannah's body, even though Drew Karpyshyn explicitly stated that Zannah won, and that he couldn't even see the ambiguity (to him it was obvious). So I hope that nothing is left to interpretation like that at the end of this.
Re: Darth Plagueis doesn't exist: I like the idea. Not so much in terms of Sidious making him up. But what if Plagueis is some kind of voice inside Palpatine's head. When you said it on the episode, all I could think was "...so Plagueis is the Tyler Durden of Star Wars. Not really existing outside the mind of his creator, and yet causing everything to happen."
