They both disappeared before (three times each), only to come back each time with a lot of fan fare. As long as the electric versions look like the originals (quite unlike the Mach-E) they'll do fine when they resurface.

Vehicles are interesting in that for the people that enjoy them there's a tendency towards brand loyalty in ways that don't exist for other products. This is especially true with the older generations. There are/have been web series, magazines, books, TV shows dedicated to Mopar, Ford, and GM. I can think of 5 "Ford guys" in my life without even trying. While that brand loyalty has waned a lot over the past couple of decades it still exists, and Dodge will most likely bring back a version of these to satisfy that base.
