I'm not trying to force it, I don't mind if Relic just makes new commanders which OKW/Ost really do need. But many have speculated that they might release a third Axis faction at a later date.
IMO it's never going to happen.
Three allied makes sense, there were three major world powers vying against the Axis in WWII. UK, US, USSR. All the others are minor.
By comparison, the only nation to come close to that level of significance on the axis side, excluding Germany, is Italy. And whilst I would like to see it, I don't think it fits the bizarre mindset Relic has about designing axis factions.
Japs were fighting a very different war on a different front and with an even heavier reliance on naval power and airforce than the brits did. Not viable for a game like CoH2, sadly. They'd get pinned by support weapons and kited by tanks and generally have a miserable time.
And a third faction that's just more sodding Germany... why? We already have two whole factions that are entirely German covering East and West fronts. If you MUST see your particular variants of Krupp Steehl shaped box you happen to be engaged to a model of, petition for the new commander system to have new units or for the ability to swap out some of your roster for equivalents like CoH1's Opposing Fronts.
