Faye got a conversion/update.
How this conversion/update differs from a remake was described here on 10th of December,

This extends her life span but also largely leaves her with the strengths and weaknesses of old Faye.
But as the life extension is sufficient far into the future she won't retire (or at least not before others).
The catch is, of course, that she has consumed time and resources for the update done, and is almost certain to consume more than "to be retired" Faye would have done.
Whether that tradeoff is good will (as always) depend on individual perceptions ex. whether the player prefer ultra busty or the old girl over alternatives and so on (the usual really).
