3.8 million total - 2.0 360, 1.6 PS3, .2 PC.
Barring another release, that's about as far as I see them getting. RE4 keeps being thrown around as an example, but each successive port added more to the game and encouraged people to purchase the game again. If it's just the three announced games and nothing more, the 6 million Capcom is talking about sounds ridiculous.
You do not have the right to never be offended.
