Just some speculation on my part, but the removal of The Whip makes me think a food service venue will go in there. Currently, Midway only has an ice cream parlor, and in the past had a food truck (most recently, this had Dark Nights drinks/snacks). If they're building a larger entry plaza for Wildcat's Revenge and Laff Trakk, this option for food would need to find a new home.
Could have seating/food window similar to the pizza place across from SkyRush. During Dark Nights, the tables were cleared out for a queue and the food ordering window had tator tots and mixed drinks, so I could see a similar setup coming here. The Whip area was already used as queue during the first season of Dark Nights, minus the ride area itself.
