Xbox 360 Update

When you turn on your 360 you will be hit with a prompt for a mandatory update.  What will this update entail?  The latest system update will address interruption issues that some Live user have experienced while playing a limited number of 360 games.  There is no new features with this update.

I hope this solves some of the problems we have with lag and such, but the only thing I don’t understand, the problem fixes a limited number of 360 games, but which games are we talking about and will this help future problems we might encounter while playing other games that are not under the heading limited number of 360 games.
