I dont think any rides will go in the foreseeable future-unless there is some major casualty on one of them.
They can imrove the rides drastically though. I agree that Colossus needs smoothening up and needs a repaint and/or retheme. If they were to repaint the tracks though, would they still be that light green, I think orange would be pretty cool. Rush's sound put me off going on it until last Saturday (yes, I know) so maybe they could quieten it down idk. People were talking about a SAW retheme, but I think it is relly cool being based around a horror movie I haven't even seen. Plus, as long as TP have a partnerhip with Lionsgate, they would not retheme it. I would like to see Samaurai and Slammer have a retheme, as neither of them have a particular theme of Canada Creak/Lost city.
Also, some of you were saying about the family rides going. I don't think that would happen now as they are now targeting families. So, no I dont think any rides are going quite yet.
