None of the rumoured coasters look like world beating rides tbf. I suppose the theme and experience will more than make up for it though.
The Donkey Kong ride is probably the most exciting for me given its new technology being used.
Don't think Islands of Adventure will be beaten by this park upon opening. That would really take some beating now.
I think the big headliner here is whatever that dueling coaster is going to be. Rumour has it that it’s going to be some sort of Mack, as Mack filed a patent for dueling zero-g rolls and has said that Universal is working on the largest Mack coaster project ever, for what it’s worth.
That could admittedly be outdated information, however… I’m not too up with the Epic Universe developments, sorry.
In terms of the IOA bit; I think beating IOA out of the gate would be a tall order. It’s my favourite park in the world, and that’s even based on my last visit being before they jazzed up their coaster selection, so who knows how highly it would sit now!
I don’t know how common of an opinion this is, but if reviews of VelociCoaster and Hagrid’s are anything to go by, I honestly reckon IOA’s ride lineup might be “firing on all cylinders” more than that of any other park in the world right now. I know that might seem blasphemous to say, but even when I last went, I would say they had at least 2 top class dark rides (haven’t done Kong) and at least 2 top class water rides (somehow haven’t done Dudley), and it now appears that they could well have 2 top class coasters in VelociCoaster and Hagrid’s too (Although “top class” is merely my opinion, of course, and I haven’t ridden VC or Hagrid’s)! So if we’re talking in terms of “breadth and variety of top class attractions in terms of ride types”, then I’m struggling to think of any park in the world that has a wider variety of top class attractions than IOA, based on reviews. At IOA, coasters, dark rides and water rides are now seemingly all presented by at least 1 “top class” ride if general consensus is anything to go by, which is something that few parks can say!
