Er, no- only the "TES-VATS" fans win. Development time is not infinite, if the game is to ever see the light of day. Development personnel, likewise, are not infinite.
So anyone whose "pet feature" gets cut over time diverted to adding VATS loses. Anyone for the whom the game is delayed so Bethesda can add every gimmicky craptastic "feature" from the last 10 years loses.
This is the fundamental flaw with the "Add everything, and those who don't like it don't have to use it" argument. Adding everything leads not to excellent games, but to Vaporware.
This is ONLY true if adding VATS to the new engine would require a large amount of code time, and I think this assumption is wrong. We have no idea how the game is coded, and VATS may be very simple to drop-into the new engine given how much development was done on it for Fallout 3 and Fallout: New Vegas. You can't make this assumption, because you don't know.
Of course if folks were advocating "Add Everything!", then that would be problem - but that isn't the case here.
VATS is a done thing, a refined system that would Not have to be recoded from scratch. Given Bethesda's history of carrying code over from game to game (including the little things and unseen things like Navmesh), I would make the conclusion based on the Actual history of the company over the last 4 games that alot of code will get carried-over from Fallout 3 and New Vegas right into the new engine, just as was done when Bethesda went from Oblivion to Fallout 3.
I'll stick with the historical facts, and with my desire to see VATS (or something similar) in TES V.
