Do we have any confirmation yet how exactly support ranks will lower the recruiting requirements?

So, how much content does this game have, exactly? How extensive is History Mode - do the various History Mode maps all taken together take roughly as long to beat as the single Adventure Mode map Hyrule Warriors had when it launched?

Do second gen characters still make first gen characters more or less obsolete like in Awakening or are they balanced a bit better this time?

Something I noticed, assuming the support list in the OP is complete..if the avatar is male and he marries one of the "regular" first gen units (i.e. none of those that can only support with the avatar, like Crimson) then you can't get all the kids because you're short one female character.

In the third route, are supports more limited or can everyone support with everyone?

That's not really something I can decide right now. In my first Awakening playthrough, it just sort of happened naturally - some characters just happened to fight side by side more often than others and I liked most of their supports, so I just S-ranked them. I'm planning on doing the same thing in Fates.

Do A+ supports basically count as S supports, meaning you can only get one of them per character and doing so locks you out of any other A+/S supports?

The Fire Emblem subreddit is just horrible. I've seen discussions about this game in multiple gaming forums and they were all pretty level-headed. The subreddit, however, just flat-out hates this game (and Awakening too, mostly). I mean, hell, I've seen people there post stuff like "I'd rather have no more FE games at all than Fates".
