I'm really interested to see what this will turn out to be.
"The Isle of the Thunder King is the new daily questing zone, with the Kirin-Tor Offensive led by Jaina Proudmoore and the Sunreaver Onslaught led by Lor'themar Theron. Doing quests will unlock the powerful Lightning Forge, which will allow Blacksmiths to forge mighty raid-worthy items, as well as classic weapons from the past. Other features will also be unlocked by your realm's participation in the war effort."
I wonder what iLvl these weapons and such might be, but I'm all for another chance to use BS again.
