I'm sorry but aesthetically nothing in the timestamp between 00:19 and 00:31 of the teaser matches up with the now familiar Sector 5(Possibly) view in the same trailer as 00:51. I'm very equipped to make that call because we also have the key-art to show us the scale of the city from other angles. Directly down-screen of the camera in the 51 view, is the reactor borders. .
I'm having trouble to parse what you're saying here. I'm not entirely sure we know where the scenes from the teaser trailer are supposed to be from, except the early shots likely being from above the plate, and given how little we've seen of Midgar really, I don't think we can determine anything based on that footage alone.
Looking at the scope of the picture below, especially the lower left part, you can see two skyscrapers similar to the ones featured in the teaser trailer during the day-light shot, and you could easily have more of those in any one of the upper-plate sectors we've yet to be made acquainted with, and have the elevated roadways be obscured between the buildings due to the fact that generally, the footage we see if Midgar is always zoomed way too far out to make out the details.
Also, elevated roadways have always been an iffy thing in FFVII, because we know they must be there for the motorbike chase sequence, and we see it even in prerender as Cloud and Co. use one of them when they leave Midgar - However, that never made sense with the general renders of Midgar in the game, as you never saw anything that suggested a suspended high-way system on the upper plates from the overview shots we were given. Yet, they're supposed to be there.
By that logic, Midgar is now no longer intended to be so chaotically built but instead mirrors the original more keenly. There's no place based on the presented scale for that elevated highway to exist, even if you were to suggest it's hidden somewhere around sector 1 through 6. My best guess is those scenes are misleads, much like the previously non-existent park that so keenly resembles the Sector 5 park. Neither do the aesthetics of what appears to be the reactor's landscape match up with anything we've seen in the trailer, or Mobius. There are not a ton of catwalk stairs going up terraced configurations. Everything is basically ground level in Mobius, with the reactors unavoidably visible amongst everything else. It feels familiar, but its still all conceptual rather than something viable.
I'd also say you're using the term "aesthetic" wrong. What you're talking about here is design of motif, not aesthetic, which refers to the style in which the motif is presented.
Cartoon styles, impressionism, realism etc. are aesthetics. The lay-out of a structure rendered in either of those styles are not.
The aesthetics match up just fine. But It wouldn't matter for the argument in either case, as again, I'm not arguing that anything in that trailer is going to be used wholesale in the game.
In fact, it's a point I'm now reiterating for the second time, which I've consistently argued on this forum for a much longer period than our conversation.
The point again - is that the assets used for this trailer are in all likelihood not assets produced merely for one-time use in that trailer, and secondly given the nature of how trailers like these are directed, that they're meant to clue the audience in on the creative intent of the people who made it.
This should be doubly apparent given that even in the second trailer, scenes from the first trailer were spliced in as well, which is not something you'd do as a director if you held that the material no-longer remained representative of your creative vision.
I'm not saying we're going to be getting the cut-scene with the avalanche soldiers in the game - I'm saying the fact that they went through the trouble of making those models, suggests the models will probably be used in the game in some capacity, which suggests we're getting a more fleshed out avalanche story in the remake.
The amount of resources - work-hours and money - it takes to make one of those models makes it highly unlikely that they'd make it just for that teaser trailer and nothing else.
Consider that the models of Barret and Cloud, which are clearly being used, were also in that trailer.
The bottom line is there is clearly material in the teaser that was meant only for the teaser, and obvious has no place in the final product. It's no more accurate than the Final Fantasy XIII teaser that played up the defunct gravity-bomb ability.
Except hey, most of the assets in that trailer carried through to the game, so that would be a perfect example of what I'm talking about here, not a point detracting from what I'm saying.
