Obviously still anyone's best guess on so many things, but based on the orientation of the footers and what looks to be the station, this is looking an awful lot like it has the unmistakable signature of a dive coaster. All of that digging just in front of the structure and the presence of just a couple of massive footers tiered along the drop seem to signal a nearly straight vertical drop.
I would also like to speculate that the actual loading platform looks like it may live somewhere in the middle of the current structure, but the initial drop will come from the same structure, but well above. Anxious to see if the structure continues to grow, or if it's reached its zenith. I'm also speculating that at least some portion of this ride will travel through darkness, be it tunnel(s) and/or inside a structure including, but not necessarily limited to the structure housing the station. Loving the new possibilities the recent news story and aerial photos have opened for our discussion.
