To be honest, this is one of the projects out there I'm the most excited for. When Universal spends money on their flagship parks, they don't pinch pennies. This is their biggest moneymaker IP too, and the site is huge. Whatever it is they are building, they are putting serious amounts of money and thought into it, and they have the experience to put both those things to great use. I know it's not a guarantee for quality, but it's a solid indicator. I'm also a very excitable person in general, so I'm prepared to be very impressed by this.
As for whether it will be an exciting coaster ...my faith is a little more shaky. Universal tore down a thrill coaster to make room for this (two, even). I don't know whether that means they've got a thrill-coaster-shaped hole in their lineup they are eager to fill again, or if they've decided that they don't need a thrill coaster on that site. I mean, Forbidden Journey next door is hardly a coaster like we're used to, but it is still really impressive and guests love it. Universal has filled two parks with screen-based rides, yet each new one keeps hauling guests in through their gates. Being completely indoors, the screen rides are also weather-independent, which is a huge plus in Florida's harsh climate. Yet they can't provide the speed and G-forces a coaster can, so it's not like they can replace coasters completely. There's also the fact that Forbidden Journey is a major non-coaster tracked ride in the area, so they'd logically want to do something different with this other ride they're building. One ride for visuals and one ride for speed, maybe?
I'd love to see a Taron or Maverick sibling built with Universal's money and attention to detail. It is clearly the best-case scenario. There are, however, many convincing arguments in favour of something non-conventional like Forbidden Journey or Escape from Gringotts, as that formula has clearly proven to work. But I think the outcome would be something massively fun no matter what it is, given the amount of resources they're spending on it.
