I feel the same way. I'm waiting to see what the next iPhone offers. I've been contract free since October around the time when the 5 came out. I'm actually just ready to see a complete redesign of the phone. I personally feel its time for a new look from the rectangular design with the antenna bordering the entire phone. May not happen though..
Sorry to disappoint you but it'll be a while before triangular or circular phones are made by Apple.
