Both female protagonists also have similar stances to their presumed original Outbreak counterparts in-game.
Yes, I have noticed this for the girl in yellow. Her face seems different from Yoko's and she looks like she's 12 years old but everything else matches : the glasses could be from Yoko:Z, the braid on the side could be from Yoko:D, her awkward silhouette resembles Yoko's, and that stance is just exactly the same, the way she keeps her left arm folded against her body is really obvious. Even the clothes, even if they're different, the style in general matches Yoko's. So she could be a new, uglier, younger version of Yoko.
The blonde girl also has a very similar stance to Alyssa's indeed now that you mention it, I should have seen it since I mostly play as her. And there's also the haircut. What bothers me is that makeup and the piercing, and her general style with the crop top and the leather clothes. Not Alyssa's style at all, and not a journalist's outfit either. She looks young on one picture and older on another so it's pretty difficult to guess if she's 20 or 30 without better pictures or the full video. If she really is Alyssa, it's possible they changed the characters backgrounds, their occupations, ages... I wouldn't be happy about that, especially since they mentioned Alyssa in RE7 as a journalist it wouldn't make sense. It could be a bonus costume for Alyssa, but characters are never shown for the first time wearing alternative outfits, so it can't be that.
The guy with the check shirt doesn't look like Jim, to me he looks like Chris Brown and Taylor Lautner had a child together, he's not even blonde, but it could be a new version of him. The fact that he's holding a baseball bat could also be a reference to the fact that Jim's good with melee weapons. And by default, there is only one young black guy in the original cast, so if this is Outbreak, then this character could be Jim. But he doesn't have Jim's stance, while the short girl in yellow and the blonde girl have Yoko's and Alyssa's, so I'm not as positive that this young man could be Jim.
And there is that guy with the Raccoon jacket. Honestly, he doesn't look like any of the males from the Outbreak cast. And he looks too old to be a college student, or a high-school student, so what's with the outfit.
He looks like he's half white half Asian, maybe, and none of the male characters from the main cast are Asian, so I would be very disappointed if he turned out to be Kevin, or any of the other male characters for that matter. So I like to think that maybe, if this game is a new Outbreak, they added more characters to the original 8 and this guy could be one of them - and maybe, the guy with the check shirt is also a new character and he's not Jim.
