Whatever theme/style they're going for, it's obviously going to be very light. There's no major theming pieces in the plans. The station building is very simple. That's not to say there'll be no theming, but it's simply going to be minimal. That's fine with a coaster like this too imo.
I don't think an Egyptian theme does it for me. Something like that could work well at Thorpe, but not for this. This ride is ALL about the height, tacking on some Egyptian hieroglyphics and whatever doesn't hit the spot for me.
Some sort of soaring bird over nature would be much better. Simple, easy to understand, makes sense. Just ticks all the boxes.
