If you've managed to go the last two years without picking up The Elder Scrolls: Skyrim or its downloadable content, Bethesda might be making it easier for you to catch up soon. A Polish retail site has listed a Skyrim "Legendary Edition" that includes all prior DLC. It's said to be coming later this summer.
The Polish site Ultima (via Eurogamer) listed the collection for PC and Xbox 360. The cover says that it includes the Dawnguard, Hearthfire, and Dragonborn packs. The Xbox 360 is listed for 169.90 Polish zloty (approximately $54), and the PC version is listed for 139.90 zloty ($45). The two are tentatively dated for June 7 in the region.
A comprehensive set with all the DLC would make sense now, as Bethesda recently said that it's finished with developing DLC for the game. Its final patch, appropriately enough, added Legendary difficulty and skills. Bethesda gave similar treatments to both Fallout 3 and New Vegas.
Shacknews has contacted Bethesda and will update as more information becomes available.
