The last boss in Sunwell Plateau instance was defeated over the Memorial Day weekend.
So what's that? 2 months from the first boss to the last including the gate pacing stopgaps.
Illidan was first downed on June of 2007. 8 months or so of no content for players at this level and now they've finished the new stuff.
The good news is, if you believe the rumors of the November release date for Wrath of the Lich King, there will only be 5 or 6 months of farming this time around.
Albion Farms and focus
