Tidal waves original theming was brilliant, but seems some of it was only thought about short term (for example the gas ball). The gas ball, I would be surprised if it ever came back to life, the piping and tanks for it were all ripped up for Stealth and would cost a hell of a lot of money to reinstall it all, especially with all the h&s there is to abide to, and more than anything the cost to keep the effect running day in day out.The others I hold out hope for, I personally can see in the future things like the q line effects, the entrance lights and the water tower working again in the future.
