Yes, but will the "high stakes cinematic action" sections be played as Grace and/or only as Grace? The chance for Leon (or someone else) is still there.
Yeah, that interview doesn't really dispel any rumors. We all know Grace will have weapons and be capable of combat. It wouldn't be a proper Resident Evil game otherwise.
She’s still just a regular person who is out of her depth. Combat is not her area of expertise which they make pretty clear, but working for the FBI, she has basic weapon training which is just their way of justifying her being competent at shooting things because it's a Resident Evil game and we're obviously going to be shooting things.
Their exact wording was that she can handle herself "a little better than Ethan" because of her FBI background, which doesn't read as her suddenly being capable of cinematic action sequences. Ethan was pretty goddamn clumsy, always getting chopped up and mutilated, which I doubt Grace will have to go through as she won't have fungus powers or whatever the hell Ethan had to fall back on.
Considering how much she's sh*tting herself, tripping, and crying in the demo where she has no weapons, her growth is more than likely to do with how she reacts to monsters as well as the typical journey every RE protagonist goes through in finding better resources and not in suddenly performing action feats worthy of such bold exclamations, especially if it's not going to deliver to an exceptional standard.
But in all fairness, we still have no idea what combat looks like in this game as we have only seen a very early stalker segment without any traditional enemies or weapons. So there's likely still a few mechanics we still haven't heard about yet that will play a part in Requiem's gameplay loop that could influence the general tone and atmosphere of the rest of the game. With that being said, I highly doubt they'll break the contrast they have established with the rookie characters by having Grace suddenly branch out into action.
I think the most fascinating thing about that interview for me was what they had to say in regards to the camera perspectives and why they made both options available. They basically acknowledge the fact that they split the fanbase in two with 7/Village and the remakes and so with this one, they wanted to satisfy both.
Combine this with the director's earlier comments about how fans will like this more than his last two games and finding a way to move the series forward, I think it signifies a lot more than people realize. We have 2 camera perspectives for 2 different types of fans. New story, old setting. Survival horror, cinematic action. New character... returning character? Not only is it very apparent they're synergizing the brand, but they're obviously trying to cater to everyone. This game essentially has the same mission RE6 had, except this time, they're likely going to nail it.
Also, rumors aside, there's absolutely no way Capcom will ship a game of this magnitude on the shoulders of a brand new female protagonist given the general sexism of the gaming industry. She’s 100% going to share that cover space with someone else.
