Should i get iphone 5 or wait for iphone 5s?

I currently have iphone 4S.

Please wait there are hardly any changes. I have 4s and my friend bought the 5 the only difference is the phone is slimmer and the screen is longer. Other than that no difference. The 5 may also be a tad bit faster but nothing where you have to die and by it. I'm sticking with the 4s until i see a major change.

Just wait for iPhone 5s, there are so many points in common for iPhone 5 and iPhone 4s.
