Cinematics and FFXIV

[Sapphic]

Neither FFXI nor FFXIV has done these "out of engine" cutscenes for anything other than bumpers and trailers for things like expansions. 1.0 is actually the exception in that it has an ending cutscene.
These trailers take a long, LONG time to make, and are wholly impractical for MMO development cycles.
And, to point out, every single example you just showed is an out-of-engine cutscene.

Incorrect. Theres a lengthy CGI cutscene in final coil.

i'd actually argue that one. It's less an independent cutscene and more an extension of the pre-existing cutscene. It's very clear they made the FCOB out-of-engine cutscene at the same time as the End of an Era cutscene. The fact that some of the details don't completely mesh with the in-engine cutscenes is evidence of that to me. They even have it that way on the YouTube channel now.

Irrelevant, only way to see it in game is in FCoB. And it expands on the story in FCoB showing what happened after the WoLs where zapped into the future, with Bahamut and how Louisoix became Phoenix.

doesn't change that it's mechanically a pre-existing cutscene given as a "reward" for beating t12.
It's the exception that proves the rule.
What most likely happened was the full cutscene was created as part of the end of an era cutscene, but when looking over it they realized "Maybe we should keep this part ambiguous?" and split it off for later. The t12 cutscene was not created with t12 in mind, t12 was created with the cutscene in mind.
Especially since the HW trailer has been shown to use out-of-engine renditions of things that happen in-engine, which tells me this will be the route they will take down the road. We will very likely not be seeing any out-of-engine cutscenes for the game ever again.
