First of all: I love your books and the original magic systems.. Your worldbuilding is something I prefer in my campaigns as a Dungeon Master: complex, which turns the traditional themes of the genre upside down.
And the questions:
1.A few years ago you posted a long post about your future plans on your website:
Do you plan a post like this again or could you perhaps describe the current version of your plans right here?
BOOKS YOU WILL SEE SOON: (The books that are done.)
The Rithmatist (once named Scribbler): Summer 2013
Steelheart: Fall 2013 or spring 2014.
BOOKS YOU WILL SEE SOMEWHAT SOON: (Working on right now.)
Stormlight 2: Hopefully Fall 2013.
Shadows of Self (New Wax and Wayne): 2014
Alcatraz 5: I own the rights again now, and hope to write this book sometime in the near future.
Stormlight 3: Goal is to write this soon after Stormlight 2
Steelheart and Rithmatist Sequels: I will probably try to do one of each of these between Stormlight 2 and 3.
Elantris 2: I'd still love to do a sequel for 2015, the 10th anniversary of the book's release.
Warbreaker 2: Long ways off.
Dark One: Unlikely any time soon.
The King's Necromancer: Unlikely any time soon.
I Hate Dragons: Unlikely any time soon.
Death By Pizza: Turned out mediocre. Won't be released anytime soon.
The Silence Divine: Will be written someday.
White Sand: Will be written someday.
Mistborn modern trilogy: Will be written during the gap between Stormlight 5 and 6.
The Liar of Partinel Didn't turn out well. Scraped.
Dragonsteel: Won't be written until Stormlight is done.
Not a lot of changes from back then, except that Steelheart got finished and Rithmatist got a release date for certain.
2. According to the Second law of Sanderson your characters have flaws, weaknesses. What is the reason, that in a lot of them (Vin, Elend, Kaladin, Dalinar, Spook, etc) the most significant weakness is the lack of self-confidence?
It's because of mode-shifting. The people you noted have been doing one thing for a long time, and are now forced into something else. The self confidence is a side effect of that. However, I wouldn't say it's the primary character attribute for any of them, however. I think you're blanketing self confidence as a larger issue, when it's the smaller part of something larger for each character.
Vin: Trusting Others
Dalinar: Conflict between the killer he was and the man he wishes to be.
Spook: Self Worth
3. And related to this last question: most of your heroes are true traditional "heroes", because they want to be useful for the family/society/other, and they often lack selfish, "dirtier" motivations. Will we sometimes see characters, who are not villains but are rather egocentric?
Expanding that, however, I feel that in general, other people are telling stories about "dirtier" characters and doing it well. I don't feel characters who are generally good characters are any less realistic, however--in fact, almost everyone I know is more like Vin or Dalinar. They want to be good people, they TRY to be good people. Fantasy has taken a very dark turn in many ways, and this is fine, but it is not the type of story or characters in which I am interested.
That doesn't mean I won't ever do it. There are some far more borderline characters mixed into some of the series, but they are more the exception than the rule.
4. Do you plan a magic system which enables the character to manipulate the four elements with their will? I mean not so bounded, like Allomancy with Pushing or Pulling but shaping/summoning the elements according to the wishes of the person. I ask this, because in the whole fantasy genre I rarely find something like this (except: Arc Magica RPG), so I had to develop it myself at home . But from the authors I know you are the person who has the creativity to do this without doubt.
Maybe, but there are a few problems here. For one, "Four elements" magic has been done over and over in books and video games, so it feels hard to make fresh. And in what you describe, it sounds like the characters would be very powerful, which makes for a challenging story to write.
5. Are the intelligent sprens like Syl the “seons of Roshar”?
What a clever question. Gold star for you.
6. As Dalinar gave his Shardblade to Highprince Sadeas, was his motivation only to free the Brigdemen as “Thank you” for the help? Or did he already plan to build a team from soldiers who are loyal only to him?
He certainly saw the side benefits. However, his primary motive was to make a statement. Not just as a thank you, but as a way of proclaiming to all of the Alethi "What we have been doing is wrong. This wealth is not worth the lives of men."
7. When will be see the whole Cosmere-concept (Shards, the plans of Hoid) at the level of the books? In the third Mistborn trilogy or earlier? In which books do you plan to finish the “hidden story” which connects all your earlier books?
Third Mistborn Trilogy will certainly include some of this. We shall see if I do any of Hoid's stories before then.
8. A bit RAFO but: Is Szeth bounded to the Oathstone (master) with magic/force or just with his honour? As I can remember, in the end of WoK he nearly killed Taravangian.
At last, I want to say thank you for your work, for your wonderful books.
Balázs, a Hungarian fan of yours
It is, as always, my pleasure. Thank you for supporting my writing.
