Never gonna happen, Closest you will ever get is mods that restore content. The Obsidian that Made New Vegas no longer exists, So it would be made by a team that would 'make it their own' or it would be handled by Bethesda themselves who would scramble it out of spite. In any case the fundamental issue is the game's engine, It is held together with Duct tape and Wonderglue A full on remake would require a complete overhaul which is 1) time consuming and 2) expensive. Zenimax would never greenlight it when they could just shit out the original game with slightly better textures and make the same amount of money at a fraction of the time and cost.I'm of the mind that New Vegas really needs a full on remake with expanded areas.
