Resident Evil 6 is weird that it's actual story is ehhh, but I actually liked most of the characters. Helena is ehhh for me (she just seems like a slightly better Angela from Degeneration to me, she has the same personality, a sibling issue that Leon comes in on, and they both are voiced by Laura Bailey anyways so they even sound the same) and it was just an okay rendition of Leon (though I do like his new voice actor quite a bit). The villains were also ehh, feel they could of been fleshed out better. However, the rest of the core cast I actually liked a lot. Chris may be my favorite rendition of him in RE6, Piers is actually pretty likable, and Jake and Sherry were actually well-done and I would like to see more of them in the future. Sherry I had hopes for her return, and she easily met them in a way I didn't quite expect, while Jake before release sounded like such a fan-fiction type character, but in practice got through via some hammy/witty writing and Troy Baker's performance, plus his dynamic with Sherry. RE6's story had a lot of problems, but I actually thought Chris/Piers/Jake/Sherry cam out as the best things from it with some pretty fun characterization.
I recall somewhere in a recent interview it being stated that there will be more action in the future, and since Capcom likes trying and experimenting with RE spin-offs, it'll probably surface some more. Whatever RE8 will be will probably influenced a lot by how RE7 does however.
I think what Capcom is going to pull from Umbrella Corps is not that people don't want action-Resident Evil, but I think most don't turn to RE for a competitive shooter. While I think Umbrella Corps is underrated right now by many and not the terrible game people think it is, I will be honest I'm perfectly a-okay if they just learn people are not looking for competitive shooters in the RE scene, and RE has already proven that there is a big market for the type of action-horror co-op game it provided in later entries.
