Two new items are causing quite a stir in the WoW Community. The first item; the "Elementium Bar" is some new type of mining reagent. Guilds running Molten Core are stating that they are seeing an as of yet non-minable node of the substance behind Golemagg. It is obvious that this item is related to the new Blacksmithing reagent "Elemental Flux" which sells for a whooping 15gold of vendors!

The second item, "Thunderfury, Blessed Blade of the Windseeker" is a new legendary sword that is the end of a highly difficult quest line involving the acquirement of two other legendary drops from Molten Core.
