Well as we know, Blizzard loves to put all different kinds of real life references into WoW and more opportunities come with each expansion!
They already have a lot as seen here:

Honestly, look at that list, and I feel there are plenty more I am expecting for Cataclysm.
1. I expect to see some Al Gore type reference, a guy running around crying how the Cataclysm was man-made and not brought upon by Deathwing, perhaps a related quest called "A Convenient Lie" or something of the sort(related to an inconvenient truth)
2. In Worgen and Goblin starter zones, I expect to see some sort of Twilight reference in the Worgen zone. Actually, we may see twilights references in the twilight highlands or with the twilight cult instead. Blizzard said the first 5 levels of the goblin zone takes place on a GTA-like city, so perhaps some grand theft auto references?
3. We'll probaly see some shout-outs to end-of-the-world movies, most likely 2012.
Any other ideas?
