SoV proves they can lay off the waifu/Avatar crap when they want.
I don't see that many legitimate concerns in other places, fine-tuning the gameplay and the dialogue + some nice cutscenes to go along and some extra Jugdral content in general like the post-game dungeon in SoV would be a great addition for me. When I say "people always hate change" I mean the super-purists I see in other websites that treat FE4 like some immaculate gem that will forever stand the test of time and should never, ever be touched because no one's fingers are pure enough for it.
So, sorry if I sounded kinda scoff-y at everyone, not my intention. I have my own concerns for it, they being changing the tone of the story or making characters into walking jokes for the sake of supports, but from what I've seen of SoV's direction has alleviated most of my worries about FE4 remakes. Of course, I'll admit I could be proven wrong, but I'd rather remain positive.
