Not much to add to what is said but, this should be good for those having random EOJ match disconnects. Here is what Jeff had to say on the Ps3 Blog.
"If you’ve signed in to the PLAYSTATION Network tonight on your PS3, you probably noticed that you were prompted to upgrade the system’s firmware to v2.17. In case you were wondering what it’s all about (and a quick Google search indicates that yes, you are) the operating stability of some online PS3 titles has been improved."
Not a big update but, it is a .07 update not even a full .1 so you can't expect much. And while yes it might not be this awesome update anything that adds stability to Online games is a plus in my book.
EDIT: This meant to say 2.17 not 2.7 sorry for the confusion.
