First, it's WW.
Second, they did the same thing with Stronger in January 2012, even though according to MediaTraffic, the album had sold like 500K worldwide (at the time). Then again remember that MT doesn't actually get ALL the estimates of ALL the countries in the world.
I'd say, considering almost 600K in the states, plus maybe some 100K in the rest of the world, it's bound to hit the 1 million mark by the new year. Maybe they just made the announcement a little early.
That is all
