As long as they fix those bobble heads urn, I mean halflings.I think seeing new materials from the older settings with the art direction of 5e would be really cool. But not if they can't really afford to do it in their business model.
As for settings I can see the majorily different settings getting an update so darksun,eberron and ravenloft I can't think of anymore of the top of my head. We really don't need to see generic high fantasy setting number 61 which varies from 60 by making dwarves lose darkvision due to them living in a giant tree.
