I fully trust The Coalition with the franchise, so what ever direction they wanna go in is fine by me. I think one of the biggest triumphs of the new game, is how it incorporated many modern elements, without it being a total reinvention, where it loses sight of itself and becomes something completely different. Gears is still totally unique, from the controls to the heavy center of gravity to the way most encounters manages to mix things up, as soon as you touch the controller, you're never in doubt you're playing Gears. It's so different from everything else. If you disguised popular third person shooters with stick figures and test levels, you might have trouble differentiating some of them from each other, but you'd know immediately which one was Gears. Gears 5 proves yet again how well the basic formula works and how engaging its universe has the potential to be, so I think it's worth preserving the series DNA for that reason alone, but The Coalition is massively talented and if they want to do it differently, so be it.
I'm more concerned about if they understand the importance of taking a break from a popular franchise from time to time, regardless of how good it is, than I am about the direction of the series.
