Heads up, this is a speculation thread, we don't need waste of space: "It will never happen" comments here.
A lot of us liked Outland and have a lot of nostalgia there, as we will with Northrend eventually. So my topic for speculation is this; will Blizzard revisit these lands in any shape or form? (New raid patches, or Cataclysm-like expansions?) Will the greatest of heroes ever return to the broken world or frozen north to combat stronger villians? Will these lands be anything more than expansion remnants, leveling zones, and pointless nostalgia?
What do you think they could do to these continents to make them important in the future, if anything at all.
