Firstly, as far as we're concerned the top two complaints about Samsung smartphones recently have been: the lack of premium build materials, and the delays in release. Well, if the rumors are true, those problems may be solved. According to the rumor, the Samsung Galaxy S III will feature a ceramic case, which may not be as "premium" in the minds of consumers as glass or metal, but should be quite solid, and not have the reception interference of metal cases. But, the really big info is that supposedly Samsung is aiming to have a simultaneous worldwide release of the Galaxy S III and launch the device in over 50 "markets or cities" at the same time. This means no release in Asia, then waiting 8 months for the release in the US. We're not 100% sure that Samsung is actually capable of pulling off a global release like that, but we certainly hope so.
Oh, and supposedly the SGSIII will also feature a 4.8" Super AMOLED Plus HD screen, but that's not really anything new or interesting. 4.8" is pretty big, but assuming the SGSIII will feature the rumored "no-bezel" that we've heard about, 4.8" won't really be that much different from the Galaxy Nexus.
The information comes from a trusted source at BGR, and we do have reason to believe BGR's sources with Samsung as the publication did get the accurate info on the Galaxy Nexus specs well before anyone else. We don't expect any confirmation at MWC, but we're hoping Samsung gives out some info soon enough.
