Could you be getting your hands on the new Samsung Galaxy S III as soon as next month?

According to sources quoted by ZDNet Korea, Samsung plans to launch the new Galaxy S smartphone in April. Although the phone was nowhere to be seen at Mobile World Congress, which has been taking place this week, the rumor apparently comes from some pretty authoritative sources. The tip apparently came from Cheil Worldwide, South Korea’s largest ad agency, who has been running campaigns for Samsung for some time.

The last Galaxy S III launch rumor we heard had the phone releasing in May.

As far as the phone itself, it’s rumored to be one of the thinnest smartphones ever – definitely the thinnest in the Galaxy line at 7 millimeters thick.

Other spec rumors put the device as having a Super AMOLED Plus display, 2GB RAM and a quad-core processor. As far as the camera goes, we might be looking at an 8 MP front-facing camera and a 2 MP back-facing one. These spec rumors come courtesy of another Korean site.

As far as another high-profile 2012 release goes, we’ve heard conflicting reports on the possible iPhone 5 release date. Earlier reports said that it could be launching at Apple’s annual WWDC in June, while the most recent rumor pushes the date back to the September-October timeframe. Either way, an April release for the Samsung Galaxy S III would beat the iPhone 5.
