1. Can Gears go multiplatform?
2. Will there be more Gears

I don't think it can go multiplatform without M$ say so, and they won't give that to them

Also, I don't think that there will be more Gears. Judgement didn't sell that well and I think they are done with that tale

People Can Fly are now Epic Poland and we were recently told they are working on Fortnite. So if they are working on it, its certainly not coming any time soon

Gears should be done imo, series was only popular because of it's graphics early in the gen, was the first real next gen looking game at the time. It's gameplay was pretty rudimentary and repetitive, rather new ip's.

From what i understand the franchise is owned by Epic buy with a microsoft contract. Microsoft decides when they want another game and to what platforms is goes.
