GOW:COO Bombs + PSP Sales DECREASE----WTF?

[Bodhesatva]

For some perspective:

The last God of War game sold less than 2 million worldwide on an install base of almost 120 million. Even being generous and assuming some of that userbase was no longer active, or many were replacement units, etc, the PS2 had at least 3x the user base that the PSP currently has.

Why should it be shocking that this new GoW will struggle to hit a million worldwide? It's not an especially popular series.
