I like that Dragonborn and.tieflings are confirmed for next paxket as well as Kender and Warforged.
Sounds like a suggestion on which might be 4 of those 5 settings:
Dragonborn = PoI
Tiefling = Planescape
Kender = Dragonlance
Warforged = Eberron
I'm not sure if the fifth could be Ravenloft or Greyhawk, the latter being maybe more popular but also more "normal", what could a "Greyhawk module" need? Ravenloft might be more suitable as an example of a setting "module" (in the current sense of the word, not the traditional one).
