Amazon Madden NFL 09 sales percentages

Xbox 360 31% (39% total)
PlayStation 3 26% (33% total)
Wii 12%
PlayStation 2 11%
Xbox 360 – 20th Annv. 8%
PlayStation 3 – 20th Annv. 7%
PlayStation Portable 4%
Nintendo DS 1%

Keep in mind that these are just sales from Amazon. If I had to predict, I’d say that the Wii sales overall for the game is probably a bit less than 12%. I suppose that isn’t terrible since Nintendo owners aren’t known for snatching up sports games.
