Not sure how recent the photos you saw were, but I saw them a few weeks ago myself and there were the footers and quite and large area of dirt that looked like it had been manipulated for the ride to go in, which makes me think coaster. Also the tower/elevator employees guessed large coaster when I asked them what they had been seeing.
Top Steel: New Texas Giant
Top Wood: Timberwolf (don't judge me..)
