After Nioh 2 having young Nobunaga, and Chronicles 3 giving us an earlier battle than Okehezama with Nagorigawa, I was anticipating they'd have some more focus on Nobunaga's early stuff, wasn't expected a Spirit of Sanada type game though.
You can see Oda soldiers fighting against soldiers with the Saito banner. Nobunaga's father-in-law, Dosan Saito, has had a unique appearance since SW1, and I've been wondering if they'll ever add him. This should finally be the opportunity to do so. I imagine his son, Yoshitatsu, will get added too. There's a good story to be told with them.
There's another battle against soldiers with the Imagawa banner. And its daytime, so I doubt its Okehazama, what with it being a nighttime battle. I take it Nobunaga isn't going to be lord at the beginning, and we'll be seeing his father, and his fights against Yoshimoto Imagawa. Hope they take a cue from Nioh 2, and make Yoshimoto not a joke character. They were already doing a split personality/facade thing in SW4, so they could go further with that.
I imagine we'll be seeing younger Ieyasu, as a hostage and friend to Nobunaga. Hideyoshi should be around, I was wondering if he was the brown haired dude in the trailer. Could be Toshiie too. I have no idea who the red haired ninja girl is. It'd be a pretty drastic redesign for Nene, but maybe it is? I want to see Yasuke in this game.
If this game is really going to be serious about focusing only on Nobunaga and Mitsuhide, then it'd have to end at Honnoji/Yamazaki. Maybe they pull a trick and have Mitsuhide survive like the one historical rumor goes, so they can go further. They did that in Nioh actually.
I'm worried about the moveset revamps. I'm going to miss Nobunaga's lightsaber. And I can't say I'm happy about Noh getting a bow instead of the claws. And I wonder how many characters we end up losing with the narrowed focus.
