From what they did on the backside of it, I imagine that is what we're getting.
This isn't the first change to the spike we've heard about either. There were reports that the brakes weren't needed at the top, weren't there? If there were brakes up there, there was probably going to need to be stairs and an emergency evacuation route from the top. Without brakes up there, there's no need for that, as we'll just roll down to the brakes below and evac on the ground.
This may have been cut for story reasons as well, making it all the more unique when the first time we enter a dark place is for the forest/devil's snare, making that climatic scene more special. Just a thought.
