Are there any Madden 07 Wii roster updates or editors?

[Dondadda]

I received a copy as a gift, but I am going to return it if there is no way to update the rosters.

Being that the Wii uses an SD card, I see no reason why there isn't an editor or an update out there, other than lack of interest from hardcore sports gamers.

The Wii version is supposedly the best Madden in years, but I'm not keeping it unless I can keep the rosters current.

Thanks!
