It's all relative to cost.
John Wick only grossed $88 Million worldwide. That doesn't sound great at all, until we learn it only cost $20 Million to make. That's why we got a Chapter 2, with a third film on the way.
So Predator will be fine if they just bring the budget down. More stories on Earth can be made cheaply enough. Even if the film went off-world, other worldly desert, jungle, and mountain terrain can be found by a crafty director without set creation (although the sets created in some cheap fan films have been very impressive).
