The rumor is the VC team is planning on it, though they obviously have no code base to work with.
1 year after release would be the earliest I would surmise.
The company is "Brytenwalda Studios".
I am sure they are only beginning to plan exactly what time period to cover.
I would guess they would move the time period slightly but have a similar map in the first release.
Place your votes.
I vote for the Saxon Invasion but that's just me.
