1.1 will introduce all three characters.
1.0a-1.0z will likely be dedicated to fixing every last remaining detail of chapter 1 so that 1.1 onward can be entirely dedicated to just plugging in the plot and art.
As I've said since the beginning of the game's development, we are aiming to make Chapter 1 as complete a gaming experience as possible and to make sure it is as bug free as we can manage.
