Ceramic cases! 2Ghz processors! 1080p screens! These are just a few of the more outlandish rumors we've heard about the mythical hardware in the upcoming Samsung Galaxy S III. With press invitations sent to a May 3rd event, speculation has hit a fever pitch, but at least one news source advises caution. Cnet quotes an anonymous insider saying that Samsung's update won't be anywhere near as monumental as some rumors indicate - in fact, it'll be positively minor. "It'll be like the iPhone 4S was to the 4," said the insider, bringing up memories of mild dissatisfaction among eager Apple customers.
