Hey, new to these boards. There is so much interesting stuff happening right now with Epic, Frisco and the UK project. Just my two cents on this:
If you look closely at the concept art, you will see the coaster seems to have a third "rail". So I assume this will surely be a (Mack) powered coaster?
Now, IF Spongebob is coming to Orlando, I'd say it's a better fit for Epic than for USF. With Dreamworks Land and the Illumination stuff, smaller kids will already be very well catered for at the Studios. Meanwhile, I always feel Epic is lacking when it comes to smaller kids. Even most rides at Dragons seem to be geared toward bigger kids. At my local LEGOLAND, the Skyfly and the coasters attract the upper end of the age spectrum only. So really, what's there for the small ones to do apart from the Dragons Splash Battle, Yoshi and Constellation Carousel?
