Eh. You can just throw in off-hand comment à la "you can pair Himiko with Majapahit in Exploration and then become Meiji Japan in the Modern Age" without revealing too much about Meiji.If it's Himiko, then she needs to be paired with Meiji Japan, and we won't get another civilization guide this week. That means the unrevealed leader isn't Himiko or Hawaiian, so he/she is probably unpaired with his/her original civilization, just like Amina and Machiavelli.
Devs did the same thing with Augustus and Spain.
The argument against that is that Himiko's ability is centered around Endeavours, and we've still don't know how those work exactly. I expect a Shaun Short on Dip before we get the Himiko FL but that might drop in the next few days.
For all we know, the next FL is Amina with Songhai immediately after, like last week's the Pachacuti-Inca double-whammy.
