There's no information on the specs of this prototype device – the first Tizen phone isn't expected to be as high-end as Samsung's Android flagships, but it should have specs that match or exceed those of the Galaxy S III (Tizen won't have as high demands as Android's, so that hardware will be enough to run the OS without issues). As for those thinking Tizen will steal Samsung's focus away from Android, don't worry, that won't happen – Samsung has said that Tizen and Android will co-exist, not to mention Tizen in its initial form won't be able to offer the same experience as current Samsung Android handsets.
