It's no surprise that Samsung is planning a follow-up to the Galaxy S III for the spring, and until recently the company managed to keep from spilling too many details on its next flagship phone. As its launch event draws closer, however, more and more details are leaking out. If the leaks are accurate, the Galaxy S4 will have a 1080p 5-inch screen, 2GB of RAM, and an overclocked version of the PowerVR GPU found in the iPhone 5. It'll also have a host of new software features, as detailed by a series of videos. We'll find out if the leaks are true, or part of a stupendous campaign of misinformation, at Samsung's Unpacked event on March 14th at 7PM ET.
