ioi has already released a statement that VG's figures are pretty accurate with confirmed numbers in major countries in Europe.
If it's under-tracked there, it won't be by much. So likely US and Europe are a near tie or perhaps US on top by a narrow margin.
These missing sales are coming from "Others" which is Asia, Middle East, and Africa.
Edit: As of Sony's announcement Europe is likely 3.8m with Americas in the 3.9m range.
