There are rumors pointing to a possible metal chassis for the Galaxy S5. It seems like having a removable back cover, with access to the battery and sim/micro sd, is an important feature to many buyers. I wonder if Samsung will stay with that design feature. The China version of the HTC One, has the removable back cover and still maintains the premium feel. With the purchase of a carbon fibre company, Samsung will be able to have phones with that kind of body. Not sure if they can ramp it up fast enough for first quarter 2014. I really like my S4 which replaced my IP5, but already planning to purchase the next S5.
