When will Apple release the iPhone 6?

I'm thinking of getting the iPhone 5S but since apple releases a new phone every year i'm thinking of waiting for the iPhone 6 because i still have a year of my contract. So can anyone give me an estimate on when Apple might release the iPhone 6, possibly spring 2014?

Apple ALWAYS, since freaking 2007, releases iphone between August to October…

so… Iphone "6"… ETA is August to October 2014

Iphone "7"… ETA is August to October 2015

Iphone "8"… ETA is August to October 2016

Iphone "9"… ETA is August to October 2017

Iphone "10"… ETA is August to October 2018

Iphone "128"… ETA is August to October 2136

shall i continue?

The 5s was released a couple of weeks ago, so you still have to wait a year for the iPhone 6.iPhones are always released in August-Early October as the other poster stated.

It would not be spring. September 2014.
