I don't think it's doing too hot. To be fair though isn't this the first bundle aimed at sports fans? And most of the Madden crowd don't play the same things we do, the bundle seems like a good idea to me.
They did have the FIFA bundle in Europe and that didn't sell too well. But they have like 2 other bundles coming out later this year too. Honestly it seems like a good deal if you're interested in the game but it will probably make no difference. People will buy and play whatever system their friends has and right now that's leaning towards the PS4.
