FilaBrasileiro on 03 September 2008
Facts:
1. As of today there are over 680k people on the leaderboard
2. You can use multiple PSN IDs and play ranked games and get on the leaderboard.
3. People can buy the game and never play ranked games.
If I had to guess, between retail + download, I'd say the sales of the title is between 600-700k.
