So y'all should buy me more red wine because I'm in a mood.
So lets do story time kids. A version of Secret Life of Pets for the lower lot at USH was developed over the years by Orland's UC group. The leaked versions of the attraction were all from them: trackless AA focus, revamped mixed media, then the "hey lets do VR on a trackless" versions was all Orlando UC. After these versions they were scrapped and the new West Coast UC took over the project and made up the current plans for JW and SLoP. I think that's why there's a huge holding pattern on the rides at UOR and we'll know more in a year. I think Orlando parks and UC are being protective and West Coast wants to prove their worth. It's also why
@Andy is being a cheerleader for USH more than normal in regards to attractions and such. It's a very interesting time for the Universal parks and I hope the best attractions, no matter who designs them, comes out.
tl;dr
SLoP at USH and UOR initial plans were killed. Then it turned into DreamWorks at Shrek and that was chucked after the projection media rejection from the GP. Now it sounds like it's going to be either a new attraction or they're waiting for feedback on West Coast's UC SLoP.
