When Does iOS 5 Come Out for iPad, iPhone & iPod Touch?

I thought that iOS 5 was going to be released today, after they announced the new iPhone but that wasn't the case.
When does the new iOS 5 come out for the iPad, the iPhone and the iPod Touch?
I've been reading about it for months now and many sources claim iOS 5 was going to be released in October, 2011 but they still won't release it.
Is there an official release date for iOS 5, when does it come out in the US?

iOS 5 and most of its other features will be made available for existing iPhone, iPad and iPod Touch devices on an October 12th release date.
According to Apple, the new iOS 5 includes 200 new features although just a few are really exciting.
To tell you the truth, I'm more anxious about the new iOS 5 than I am about the new iPhone 4S.
iOS 5 will have so many new features to play with it, it will actually change the way your iPhone, iPod and iPad work.
