The new Fury is the one that Marvel wants to push, which is perfectly fair because Marvel is pitching to audiences who found comics through the movies.
The only way for old Fury to come back is for the current run of movies to end and be mostly forgotten. Then, there would need to be a push from (or supported by) editorial to use the old Fury. My guess for that sort of time table would be at least 5 years, probably more.
