An official Q&A regarding the next FIFA 10 update has been posted over on the EA forums – you can read it in full if you click here.
Basically, a squad file is on the way that will fix the broken tactics in the game (e.g. all English teams below the Premier League having the exact same all-70s tactics), as well as updating some of the existing tactics to make teams play a more realistic game of football based on all of the community feedback.
It will most likely be arriving over the next few weeks, but it will fix nothing else.
