DC/Marvel Big Event Emulation: Doing the Math

Today:
(M)Fear Itself = (DC)Legends, as a factor of World Turns Against Heroes + Godly Involvement, but consider that (DC)Legends = (M)Mutant hysteria + New Gods

(DC)Flashpoint = (M)House of M, where M = F

Previously:
(M)Chaos War = (DC)War of the Gods + Blackest Night, but consider that (DC)Blackest Night = (M)Marvel Zombies + Green Lanterns

(M)Secret Invasion = (DC)Millennium, as a factor of Enemy in Our Midst

Of course, (DC)Final Crisis = (DC)Infinite Crisis = (DC)Zero Hour = (DC)Crisis on Infinite Earths = Pop Will Eat Itself

Even earlier:
(M)Secret Wars = (DC)"The Final Challenge" in Challenge of the Super-Friends

Predictions based on model analysis:
(M)x = (DC) Invasion!
(DC)x = (M)Acts of Vengeance
