Limit 1 Facepalm Per Turn
It'll be a relief when they tell us. Chances are it will be something that didn't take a whole lot of time to implement and balance (since they've chosen not to market this civ's ability until less than a month before release), and yet the game changes almost entirely with them (since they've hyped it as going beyond merely outside-the-box).
My stab in the dark is that something core to the game will be automated in some way when using this civ. For example, there are no tech buildings or beaker acquisition, and instead the civ gets a tech 10 turns after it is first discovered. Except I'd hope they could do better than that particular example
Another cool idea (though I do not think this is the civ they're talking about and it probably wouldn't work in practice) would be to have no buildings at all, and acquire everything (units, techs, SPs, wonders) though gold purchases. Even cities could be taken out in favor of starting with a worker that can build a special improvement that puts a tile in the civ's territory and adds gold yields to it (workers would need to escalate in price to prevent the civ from expanding too quickly later on). In that case, purchasing a wonder would simply put it somewhere in the civ's borders. Actually, so few wonders would be useful to this civ that it would probably be better if they couldn't buy 'em after all.
