I have a feeling that the Gen 2 armor sets are going to return in some capacity.
Seeing as the art style for 4 and 5 are nearly identical, I can’t say for certain which Venator style will make an appearance. But honestly looking at the two the difference is incredibly subtle, but there will most likely be a Venator regardless.
I think I can see which two are supposed to be EOD and Enforcer. I think the EOD helmet will have an attachment that will make it have a stronger forehead and reduce the visor size, similar to how the GUNGNIR Gen-3 Helmet will be.
At least we will have the classic versions in the Mark V Bravo Armor Core. (I wonder if we will also receive the AKIS and Mariner helmets?)
