As boring noted, the market for feature phones/basic phones is such that most manufacturers are not focused all that much on the segment. The only feature phones that will be able to be brought onto the VZW network, and remain active in 2020, are listed in the link. If any new models are added, they, too, will be able to go forward.
The Kyocera DuraXV LTE is the "newest" phone and that was released 16 months ago. Anyone expecting new models coming are going to be disappointed.
