Bah people think a second game could be a thing... I don't know about that.
People that think about exposition in October? before the alpha tests? that makes no sense. Though it'd be interesting to see what actually comes of the game if they where to say October would be exposition. Sure they said the game would launch in December when kick-starter happened but they have only been in production since the beginning of the year. That would be very interesting indeed to see this game develop so fast, I don't think it's remotely possible.
The overall shape of each continent and where mountain ranges are would be awesome to see.
Prologue would be cool, but some people want the prologue to also include the majority of jobs and weapons. So that seems likely. but I doubt it'd be anything like that.
So my 2c will be as follows, a discount on spark of life and carriage for two, as those are the things that aren't discounted right now, and the theme for promotion is discounts. and everything is discounted by 10% I could see those at 10% or some other odd thing about it.
Though that's predictable and not really a surprise. So it'll likely include the domain selection.
Things that need to happen before land selection.
NPC and OPC details and roles.
resources exclusive to each biome, and what areas can have tunnels, and what you need to be able to support a home foundation and tunnels.
Where each biome is located on the maps.
The various job descriptions and what they need to be successful, and how the mini-game works while crafting.
how guilds work, and what it takes to make a guild branch.
where ruins are planned to be located.
