It's important to note that the metal chassis rumor is just that - a rumor. There's been no confirmation at all from Samsung, the story came from industry insiders'' which could mean absolutely nothing. But considering Samsung's penchance for removable batteries and replaceable cases, it seems highly likely (to me) that the metal chassis would be an option only (or the front of the phone might be metal and the back could be plastic or metal). The HTC One's design is one of it's best features and a large part of that is the metal case, but plastic protects a device better from a fall so it seems a little unlikely to me that Samsung would make their phones more expensive, less durable and with a non-replaceable battery (if it was a solid shell case), especially considering how popular those features are for them right now. Carbon fiber or Kevlar would make more sense (and be lighter).
