Another Galaxy S III prototype spotted in protective casing

While we've already gotten glimpses of supposed Samsung Galaxy S III prototypes, this latest one has popped up in a (since removed) post on Chinese forum Mobile01. The plastic rim meant to obscure the device's sleek new design is still present, but as noted by The Verge, the picture appears to show a larger menu button than we're used to on stock ICS. We should find out what the deal is in just a few days, we'll keep our apps and countdown clocks close by until then.
