Kristoffer may or may not add these nations at some point. He was intending to do something about EA Machaka, but then the Jomon updates sort of ran over that.

As far as Machaka goes, it has plenty of African mythology on it. EA would also have, though of a different bent, since it would likely concern itself with the earlier stuff (immortality, cloud people, the coming of death etc).

Vanarus, well, aside from two units that are already in the game, no idea what its status is.

Any possible updates are likely to be infrequent and random now that they are working on the new project, whatever it is.
