iPhone 5c update?

Everyone's been talking about the iPhone 6 and what it's going to look like. Being one of the few that prefer the 5c's body over the 5s's, I'm more interested to see what the next version of the 5c is going to look like. Do you think Apple will update the 5c at the same time as the 5s? What will the next version be called? 6c?
