OK, an attempt for today:
Jackson, 2021
Current Affairs
The world continues to grapple with a Coronavirus Pandemic
Divergence Point

Major Civilizations
Western (Multipolar), Chinese (Empire [with Rivals?]), Orthodox (Empire with Rivals)

United States (Representative Democracy, CR3?), People's Republic of China (Dictatorship, CR5?), Russia (Dictatorship/Oligarchy?, CR4?)
Potential Great Powers?

Worldline Data
-> TL: Late 8
-> Mana Level: None
-> Quantum:6
-> Infinity Class: P5
-> Centrum Zone: Red

Notes: I bent towards fewer great powers and major civilizations, as none of the modern timelines listed had more than three civilizations and five major powers. Indic might need to be included in there. I'm unsure if Taiwan is enough to qualify as a rival, though if you take a broad Chinese civilization (as IW does) then it's rather definite, with Vietnam and South Korea charting anti-PRC political courses. I'm kind of fuzzy towards CR ratings.
