My understanding was that he and the others were simply screen shots done in the same digital imaging as the rest of the ride. If the ride is 3D similar to Spiderman, it should be convincing and fun.
I hate to say it, but the posted video did sort of remind me of the Simpsons ride or Back to the Future in that it's one long chase through multiple areas of film in a moving vehicle. As cool as that may be, it's a bit disappointing. One of the best things about Spiderman is that it includes set pieces that are quite spectacular, along with with 4-D effects, and a narrative that becomes more and more clear with repeat rides. It's the whole package that, to me, sets it apart from any other attraction of it's nature.
It's quite possible that these elements were not visible in the posted video but still present. Hopefully they are there and riders get to experience them and not just the video effects.
Additionally, this ride seems to be much more of a thrill experience than Spiderman. So TWWOHP has 2 of 3 attractions that cannot accommodate riders under 54 inches and TIJ cannot accommodate larger passengers? My wife can't do thrill rides of any sort. So she can shop?
I suggest that TWWOHP, as spectacular as it appears to be, suffers from the same flaw as IOA in general. That is that the ones who pay the bills can't join the kids on many of the attractions, and that the coolest theming in the world (IOA really stands above everybody else in theming) won't bring back return visitors. We are dying to go and see HP, but unless I am mistaken won't return for additional visits. And I really think that is IOAs problem with the entire park. It's really for teens alone, or for teens with parents who can withstand G forces and frequent near drowning.
My favorite memory from IOA involves the defunct Triceratops Encounter. We visited as a family and the big robosaur "sneezed" on my daughter. That had nothing to do with thrills or theming. It had to do with a simple attraction that allowed everybody to visit together having a cool memory moment. And they closed it down. I don't begrudge the loss of a single attraction anywhere, but I use it as an example of the fact that IOA is destined to be a long term also-ran in Orlando because they are very specific in the type of audience that they want to attract, and they treat anyone outside of that demographic as an afterthought. If they can be satisfied being the 7th most visited park in Orlando then more power to them. But they could be capable of so much more.
