Since Maxis has more or less been gobbled up by EA I don't think we will ever see SimCity4++, so I think we DO need another city sim.
There are a few in the works but I don't think any "carry the torch" of the SC4-style game.
SimCity 4 has such staying power, new mods and lots are still being created to this day! It outlived SimCity 2013 by far.
Cities: Skylines, Banished, Citybound are all fun in their own right but I don't see any as a proper continuation of the SimCity series. (ignoring SC2013)

As a bonus you can play around in Kotlin too!
