Plot wise? more alt-history where the japanese win most likely.
I imagine that they'll go on to win the Solomon Islands campaign and Leyte Gulf.
Coming from a game like Pacific Theatre of Operations allowing you to forcefully conscript slave labourers and sexually enslave comfort women to something as sweetened and sanitised like KanColle, I feel like we've seen the full process of willful indifference in Japanese mili-otaku culture.
They're better off with doing slice-of-life "cute girls doing cute things" with yuribaiting, and I'm betting that it's what they'll do.
Dunno about Azur Lane. It's not dying, but it's not growing explosively either, which means there's little chance of money getting thrown their way.
