iPhone 5C 2?

I have seen people posting recently about the future of the rumored iPhone 5C. I don't think that there will be a second generation iPhone 5C, because I think its purpose is to bring the 4" screen and lightning connector to all the phones. Next year the three phones would be iPhone 6, 5S, and 5. All these have the 4" screen and lightning connector that the 5C is supposed to standardize.

Basically I think there will be no second generation to the iPhone 5C. What do you think?
