Uh, just because it's old, doesn't mean it's less valid at all.
Although, they never actually said they wanted to sell 5 million in general. It was just implied. Which, again, doesn't really match up as a "valid" piece of evidence showing Capcom wants to sell 5 million.
Besides, 5million is a very ambitious sales figure for any game unless the game is COD.
I kinda doubt it since there were torrents for the game on the PC version. When I looked at it, there were around 20k leechers when it was first released. Most likely more people found out about it and continued to download the torrent, as well as other torrents from other sites.
Wow, that's quite a lot of potential sales to lose out on. But then again, do people who torrent buy games anyway? I guess it would depend on the game. I'm not going to say all users of torrent pirate everything.
When Capcom/NT put DmC on the PC, they probably lost potential sales because of how easy it is to pirate things on the PC. I'm not entirely sure though.
