Question on campaign flow

I read somewhere that the single player campaign will be something like a turn-based system. Every turn will jump the game forward like 10 years, is that true?

I ask because I was curious if there was going to be a difficulty setting available? I was thinking that the most difficult setting should only jump the game forward like a month or so.

Real time, according to this post:

Yeah, current plan is pausable/speed adjustable real time.

Turn based could work, but not with decade turns, that’d be impossible to play!
