iPhone 5c, best selling iPhone yet?

So I have a feeling the iPhone 5c will sell a lot more then the 5s. In the US, which is Apples biggest market they now have a 'new' iPhone that costs $100, it comes in very playful colors and is overall a solid device. Before they couldn't market their cheaper devices but now they can.

This will be a deadly combo and I feel and the iPhone 5s will just be left to the bigger spenders and wanting to be on the bleeding edge of Apple. Off course outside of the US the price difference won't be as big I predict, given that here in the UK the contract prices of the 5C are already as high as the 5 was at launch, if not higher.
