Probably not. Too much money and power invested in F1, and even despite the boring Tilkedromes that have come to dominate the schedule, it'd be hard for Formula E to compete on quality of tracks. More likely, we'll see a continued progression towards increased use of hybrid systems - more powerful KERS, bigger batteries, decreased fuel tank size - which might at least cause Formula E to become a useful feeder series for drivers (perhaps if the driving style starts to become dramatically different?) and especially for engineers.
