Update: According to CD Projekt RED director of public relations and global communication Michal Platkow, “There’s no Enhanced Edition of The Witcher 3: Wild Hunt that we are aware of, this is some kind of error that we will look into.”
Original Story: French retailers E-Leclerc and Amazon France, and Belgian retailer SmartToys are listing a The Witcher 3: Enhanced Edition due out for release in Europe on February 5.
CD Projekt RED usually releases Enhanced Editions of its The Witcher games with new features and upgrades. These upgrades are usually made available to existing owners of the game free of charge.
Thanks, NeoGAF.
