The article doesn't specify if it's sold to consumers or shipped, nor does it give a breakdown on each title. I have a feeling it's shipped though.

Well done God of War, this is the first time I've seen the sales of the series outside of VGC. Combined with COO and Collection it's a 10 million seller franchise, well done.
