Yesterday EA tipped off that a patch is in the works for Madden 08 by releasing it prematurely for the PS3. As it was not complete it caused some problems and was retracted later in the day. Also the rosters on both the 360 and PS3 were rolled back to the original default set. It isn’t known whether the two issues were related.
There was an update today to fix the rosters back but that does not represent the final patch that is being worked towards.
By releasing the patch before it was ready EA let it be known that they were actually creating a patch, which is something that had been expected to happen but not yet confirmed.
It is unknown what the patch for the 360 and PS3 will entail, though it seems likely it will address the high frequency of fumbles during gameplay and the glitches within franchise mode. Those are the two topics which have dominated discussion around the game since release.
No ETA has been given yet on when to expect the completed patch for the 360 and PS3 versions of the game. Once it is released I expect to have the details of what it specifically addresses.
