I'm absolutely with you. And Coalition are the right team to do, they've shown immense talent with 5, but it's clear it's been pushed as far as it can. Everything needs to be redone, get rid of the stop and pop gunplay, the exaggerated, bulbous, character models, throw it all away and start afresh. Re-establish Gears, start with its base tps gunplay, quick reload, bring in some of their new enemy types like the Warden as it's foundation but spend a year or two recreating it's combat. Put it aside for 5 years, make it special.
Would love if they went down the horror route personally, and don't make it about locust/demons with boots, it's boring. War about something else. BotW, GoW even Mario Odyssey have shown how you can thematically be familiar yet mechanically still reinvent yourself. I don't think there's an appetite to revisit more of the same.
