In all seriousness, a new Skyrim: Ultimate Next Gen Edition would sell and be really welcome.
Mods have proven how incredible the game's graphics can look, how new spells and perks can enhance the gameplay, and how much further the game world can be exploited to add new quests, new NPCs, new weather systems, new locations, and much more.
The mods aren't a theoretical proof of concept they're working and complete as of now. Bethesda could bake in the top 200 mods, 4K 60 FPS, and they'd turn a 9 year old game into unquestionably the greatest RPG in 2020.
