What's a Seawolf?

YES!

I know a lot of people were excited for Eshonai flashbacks, but I was always so, SO concerned how that would play into the main story.  (With her being dead and all.)  I really, really hope Brandon goes with the idea of Venli flashbacks instead.  The flashbacks in the first three books tied into the main narrative so perfectly, I just can't imagine how that could happen again with a dead character.

Also, with Dalinar going Super Saiyan at the end of OB, I have a feeling he's in character group three, as any further major revelations with his maybe sorta who knows mini-ascension would certainly be saved for book 5.  I have no clue for character groups one and two, because I can see Kaladin and Venli as being in either one.

Has he commented on the 'secret project' listed on the progress bars of his website?

Because if not, that screams Cosmere to me, especially in light of an elsewise two year gap
