There is also an unsed 'Songs of Arabia' DLC listed there.
Sons of Abraham is an intersting title, and while it could really be anything for any of the Abrahamic religions, in my opinion it does suggest something leaning towards Judaism, though I'm not 100% sure. I would think that if there were a solely Catholic/Papcy/Cardinal/Holy Order/etc. focused DLC it would have a title more... Christian-centric, but "Sons of Abraham" seems to indicate something not as much. This doesn't mean there will be Jews, but it perhaps could mean a revamp of the Crusades/Jihads, for instance, or holy wars, or anything religion-related, really. We'll see.
My CKII Mods:
Vanilla Immersion, Events, and Traits (VIET) - A modular roleplaying, flavor, and tweak mod! Part of the Historical Immersion Project (HIP) consisting of PB, SWMH, ARKO, and NBRT+
Cultures and Portraits Revamp (CPR) New portrait sets and other portrait enhacements - no more Arab portraits everywhere! Now a part of HIP.
VIET Music - Hundreds of songs to enhance immersion, ranging from authentic medieval music to traditional Persian music and West African ballads!
Stop the Orgy, Please! - Nerf seduction rates (uploaded by request)
Old Age - old characters are weaker and less capable: no more 80 year old kings running around like they were 20!
Jews Everywhere (JEW) - New Jewish cultures and courtiers, ranging from the Mizrahi to Chinese Jews.
Too bad that even if this is the case we will not get a confirmation until the end of October or mid-November.
I don't know what my brain wants to think. It feels really weird.
Also, It's not that odd if you consider the literally thousands of topics asking for the Jewish religion to be implemented. But As I previously said, I don't think it's going to be any religion exclusively. I think it's going to be updates to Islam Christianity and the implementation of Judaism.
If it's indeed called "Sons of Abraham" I don't think it would be focused only on Catholicism. I'd expect at least Judaism as a side feature.
Maybe it's a DLC about apocalypse.
All three "sons" of Abraham join the battle at Har Megido
New characters added: Archangels, Horsemen of The Apocalypse, Satan, God...et cetera
...I want it. True. But so does another 350.000 people. Catholic would seem more ... Logical, I guess. Jews are a much smaller religion, though I'd love for them to be fleshed out. Just later.
A Judaism DOC seems a bit odd. Is there really enough material to justify a DLC for this time period? Also during this period (9-15th centuries) Judaism was really diverse - Khazar kingdom level tribe tribe, maybe an Ethiopian county, money lenders and merchants in Germany and NW Europe, courtiers in Muslim Spain, some urban communities lacking any real political power throughout the Middle East, etc. It would just be a huge hodgepodge of mechanics to try to cover these, only one or two would hardly justify a DLC. Many of these really would make more sense as part of other DLC mechanisms (such as perhaps Jewish merchants and money lenders as a small part of an economics overhaul with borrowing and Catholic anti-usury laws, etc. and maybe introducing royal expropriations and banishments of wealthy groups like Jews or Templars.)
