Madden spokesman Rob Semsey said in an e-mail today that Favre will have an overall rating of 82.
Wednesday's update will add Favre to the Vikings' roster after it was announced he signed with the team today. Vick, meanwhile, will have a 73 rating -- significantly reduced from his overall Madden 08 rating of 90.
Based on EA's "If it's in the game, it's in the game" slogan, one can only assume that if you're using the Vikings in franchise mode, you can fully expect Favre to retire at the end of your first season, be trailed relentlessly by Rachel Nichols, be featured in a series of recurring B-roll footage of him tossing lob passes to Hattiesburg high schoolers only to return just as you were thinking to yourself, "Wow. He's really doing it this time."
