While I do think a scenario for Survival horror during the day and in a very hot place, with desert atributes, etc could without a shadow of a doubt work well enough for a RE game, unfortunately i don't think that will be the case for the next chronological game.
From what i gather the next game will most likely feature 2 very distincts areas, one with a more traditional scenario for RE games and the other turns out to be very atypical from what we usually experienced from all previous RE game...
(and i think the next chronological game telling the events after Village will be denominated just as something in the vein of Village too, and that this codename will unabashedly be a reference to the next big threat or secret black project that characters will have to combat.
And in my mind i tend to imagine the characters from this game will -for a good portion of the game - need to figure out a big conspiracy, and this will prove to be way different than what RE 7 and RE Village gameplay provided, and that will be the biggest theme for this new scenario/environment of this next game... )
And the Remakes, the next one they should do if they don't want to risk spoil the formula should be a trilogy of remakes, start by picking RE Zero and RE 1 and make that into one new remake, call it Resident Evil: Prime Infection, while properly fuse this section and make Rebecca scenes more consistent throughout the whole ordeal of these incidents and properly tell the story between Wesker and the Stars to this new generation of gamers.
They could also fix the ending of this game showing us the ending that was lacking from RE 1 Remake 2002 (that is, an ending that actually show all the 4 survivors being rescued by Brad: Chris, Jill, Barry and Rebecca... This would be definitive take to go along with the remakes of 2, 3 and 4...
This would properly set up the stage for the next remakes, that should be Code Veronica which certainly needs to be the follow up game that can really flesh out Wesker and Chris rivalries and provide the proper hype for a RE 5 remake to conclude everything in terms of Remakes.
I am not saying RE 6 is not worthy of a remake, but.. I think by the time a RE 5 remake closes that next trilogy of remakes, it will be hard to sell RE 6 next, as the way I see it 6 seems the very odd game because it has adventures from too many characters but with the caveat of having all out new villains that I don't know how well they could pitch and market for the new generation, unless they make the 6 remake deviate radically from the original 6, perhaps sell it as an Ada x Evil Ada Clone thing
A RE 6 remake like this could easily backfire and in turn the critics and public could both rate the remake as bad and also consider the remake trend something tiresome by that time, so it probably wouldn't sell as much as the other remakes.
But maybe I'm wrong and down the road they find a way to make a RE 6 remake more palatable to the masses, who knows?
