In a dev video covering skins and events in 2020, it was revealed that the target number of skins to be released is set at 120.
The following champions were mentioned by name as having upcoming skins in the works:
A preview of a few of these champions' future skins were shown in the form of concept art throughout the video.

Some of the less popular champions have been waiting several years for a new skin to be added for their smaller but dedicated player bases.
The popular champions such as Lux, Ezreal, Ahri and Kai'sa will not be left out, with further additions to their skin collections also expected.
With only a few thematics universally loved across all regions, some skin lines are noticably unpopular in terms of both purchases and usage in-game such as Snowdown.
The possibility of bringing back further old skin lines, as High Noon was last year, is something Riot will be considering doing again in the future.
Mecha Kingdoms is the next collection and first major event of the year, coming as an alternative to Lunar Revel. There are five 'pilots' at launch: Draven, Garen, Jax, Leona and new champion Sett, with the first Prestige Edition of 2020 available for Garen.

A revamped system for events and Event Passes will also come alongside new skins, preventing the need to grind for a month to unlock all of the rewards.
The champion-based stat tracking system called Eternals was revealed last year and due to backlash, it was delayed in order to revamp the plans.
A new Starter Series that can be bought for either game currency permanently for a particular champion, tracking takedowns, structures destroyed and monster takedowns.
Further updates will bring Ranked Split exclusive Eternals allowing players to bypass the RP aspect entirely.
