its a fact that Capcom is making this game, and all evidence suggests it will be a nextgen title (PS5/Xbox Scarlett). 7 was more of a self-contained game in terms of story but i hope they try to extend their scope with 8 but most importantly bring new mechanics that change the way fans of the survival horror game genre feel.
I understand that many fans consider RE 2 Remake the pinnacle of RE in terms of gameplay... things like the aiming precise shots and how the developers fine tuned the difficulty so zombies are tougher and smarter, Mr. X menacing presence felt throughout the entire game, etc... These elements are awesome but i also expect 8 to throw unexpected things at the player...
for instance: completely surprising missions suppose your character finds a baby and in such scenario you must ensure the baby survives and returns to its mother... you have to carry the baby in a bag, but once in a while the baby will feel hungry so you need to give his baby bottle or else he will cry very loud and because of that monsters hear you and will attempt to take the baby from you. But also the baby could provide an important stealth element since after feeding him twice he will need to pee and you can cover yourself with his pee and the smell will trick enemies similar to lickers into thinking you're one of them temporarily allowing you to escape. after a while you succeed in taking the baby to his mother and she gives you an item for it, but if the baby dies his mom tries to kill you and you will end up wasting your ammo to escape and get zero items in return.
Other zany situations to add to the plot: after completing 1/3 of the game your character obtains a special weapon that charges itself with monster dna, so killing a group of 4 monsters you collect their dna to charge the weapon but when you use the weapon it has 3 possible outcomes: one is you shrink an enemy so he becomes weak and easy to kill with a knife or one shot, another is you turn the enemy into a walking bomb (he explodes after 2 seconds and hits whatever is in his proximity), and the third is that a few specific monters, like dogs or wasps, can be hypnotized by this weapon and this enables you to perform actions with them temporarily, letting you break walls, or activating traps to help kill other monsters, etc.
