Warhawk sold more than 400 000 units in EU alone!

Yes, this is not including japan sales.

You expect over 200k of the "registered" are rented? Once you delete your warhawk data on your HDD you off the list.

Rented, or re-sold, or borrowed, or multiple PSN accounts on the same PS3.

It's possible this is drastically undertracked, but you honestly have no clue how significant or insignificant those above factors are (nor do I). There is no way to know what you're stating as fact, and I'd wager it's extremely unlikely that the game has sold over a million (or even 750k) when the above factors are taken into account.
