The moment is too iconic for Square to resist showing it off in full remake glory though. I really don't think they''re gonna screw with that kinda thing.
You want Tifa to die?
No...I'm saying that the original scene is too iconic, to the point where its one of the few flashback that Advent Children ever bothered with, helter skelter as it was. It's probably one of the most youtube moments from the game as well.
Square would be hardput to resist recreating that scene and going "See? We can make you cry the same way as when you were 10...IN HD 4K 60FPS!!!!"
