I kinda hope this new RE2 ends up having a visual fidelity similar to Until Dawn.
I realized this when I played RE5 Lost In Nightmares. Seeing the RE1 mansion replica with a 3rd person camera and almost no loading screens reveals just how small a place it really is, if it is in fact the same size. This is one reason why a 3rd person RE2 would have to essentially have an all new Raccoon City designed from the ground up. I'd imagine it being more like an open-world game, or at least an old-style adventure game scaled up to the proportions of an open-world game. Maybe Silent Hill 1 is a good comparison, but even bigger than that.
I don't really trust modern Capcom to make a completely new RE2 that wouldn't piss off fans of the original though.
Something to also mention is that Resident Evil games, and most old survival-horror games, their locales aren't actually that huge. You could easily map them out, there game-time is extended because of back-tracking, puzzle solving, monster obstacles, scared to move on, etc., and Resident Evil 2 in particular is shorter than your regular Resident Evil game. While the A/B scenarios and extras make up for it, it is definitely the shortest main series Resident Evil game. They can be sped-run in an hour and a half, if you know what you're doing you can beat a scenario in 2-3 hours easily, and even the first run will take most people somewhere between 4-7 hours. Resident Evil 2 has some really easy puzzles, and smaller locations than the average RE game. It makes up for it again in creative monsters, great music, interesting RE story, replaybility and extras, but it definitely is not a long game.
