With the recent rumours about a possible “HD” version of Skyrim, and a possible announcement this Sunday the website base.com may have leaked it earlier than expected indicating a launch date for November 23rd.
A definitive edition for a game is pretty much an updated version with higher resolution, usually 1080p / 60 frames per second, all previously launched downloadable contents and updated textures.
It should come out on Xbox One and PS4.

All we have to do is wait and see if Bethesda announces this Sunday. Until then, stay with us!
