"Michael Pachter, video game analyst at Wedbush Morgan Securities, believes the longer the lockout drags on, the more likely it is that NFL fans will become alienated. He said while Madden is a great experience for gamers, its sales are definitely correlated to the underlying popularity of the NFL, so if the popularity of the NFL suffers, it’s likely that sales of Madden will suffer.
“It’s still too early to call, since the lockout is happening in March and Madden launches in August,” said Pachter. “That’s a lot of time to fix things, although most commentators don’t sound very optimistic. My guess is that a complete cancellation of the NFL season would cost Madden around 50 percent of sales, and a delay of the season would be far less impactful. If the season is only delayed a week or two and fans aren’t alienated, there would be only a very small impact; if delayed through Thanksgiving (when the holiday selling season begins in earnest), the impact would be far greater
