My two cents, FWIW (which probably isn't much!):
I think it's unlikely that the company adds pre-booked LLs and then calls it something different from WDW. There would have been no reason for them to change the name of the program to match WDW (but not change the functionality to match), only to then change the name again so that it doesn't match WDW (but then change functionality so that it does) - this would be very illogical to me.
Pre-Covid, from what I understand, WDW was making a killing on the "upgrade to Club Level and get 3 more Fast Passes for extra $$$ per day per person." It never came back after Covid, but, is indicative that they have experience already offering a plussed version of whatever the current line-skipping program is. This is key: this company always wants more ways to increase margin and take on additional revenue for something they essentially, already offer, just slightly altered.
That being the case, I think this could possibly be some form of "competition" to Universal Express Pass. Why?
1) Whether you like LLMP, or liked
Genie+, or liked MaxPass, or liked FastPass, they all had (at least) one problem in common: varied levels of confusion, that with changes required more and more time on a screen, when you should be enjoying your park day. Express Pass kills off this problem.
2) Touching again on confusion - the average person finds the program (and past programs) confusing and hard to use. Express Pass, again, fixes that. You purchase it (either single use per ride or unlimited use), enter the park, and have at it: no return times, no planning, no refreshing the phone -- just use it.
3) While comparison is a fool's errand here, b/c people inevitably like one or the other better, and because the systems are inherently different, Express Pass unarguably requires less time on the phone (if any) and is simpler to communicate. This is something Disney badly needs for its line skipping program.
I don't think this replaces what is there at either DL or WDW. Whether we think they work or not, Disney isn't going to suddenly replace the LL program they JUST rolled out at WDW, nor the current one at DL where arguably it works quite well (certainly compared to WDW). I envision this being similar to Express Pass, but likely only available as an additional add on, or maybe even more unique, as something you can buy (like Club Level FP) if staying at XYZ resort.
