By "two timelines at bay", you mean the original and the Remake one, right?
Then absolutely not. Ma dude, Zack is freaking alive, there's no way things are gonna end well. I just hope Trey-, I mean Vincent (same voice actor, hehe), is well done like the Turks have been doing (speaking of which, it's sad Reno won't be much present due to the death of his JP voice actor, but at least he won't be completely gone thanks to pre-recorded stuff. Plus, he barely appears around at this point in the game because Elena replaced him), and not ruined like everyone else is been suffering.
