well, doing the initial questlines for 8.3 on the ptr had several "AWESOME IN GAME EVENT:" cutaways. maybe for them?
That placeholder text has also been used for scenes that involve your character rather than a cinematic.
One is for Wrathion and Anduin talk in Stormwind when Magni also appears, probably the short one. The other one is N'zoth's death. You're welcome!
Nzoths death and maybe an epilogue?
I personally had zero problem with launching a giant final flash straight into squid Bois face. I really hope they didn't change that. Maybe just make it a bit more epic.
Goody, two cinematics! They'd better be of the in-game cinematic quality, not the cutscene stuff with game models.
vulpera cinematic? (I hope not)
One is for when N'zoth is defeated and the other is for some Wrathion parkour
One is definitely the end of raid cinematic that we always get. The 2:19 is probably end raid. While the 59 second one is probably a rising of N'zoth cinematic similar to what we got with HFC, Gul'dan summoning Archimonde and then his death with everyone united.
