We all know it's coming, Samsung's next Galaxy smartphone, but when exactly will the South Korean device maker unveil their Galaxy S IV. Last year we saw the Galaxy S III unveiled at the Mobile World Congress event held in Barcelona, and it looks like we should see a repeat of this early next year.

Mobile Geeks have the scoop, with a "Samsung insider" whispering to them that Samsung wants to unveil the Galaxy S IV officially at MWC 2013. MWC is the world's largest wireless trade show, taking place between February 25-28. Samsung plans to reportedly hold a private launch event for the S IV, which could be part of MWC itself, or held separately, this isn't set in stone just yet.

Once announced, it shouldn't be too long until physical availability happens - which should be in Q2 2013, sometime around May. Rumor has it the Galaxy S IV will sport a Full HD 1920x1080 display, an ARM Cortex-A15 CPU in the form of Samsung's Exynos 5 series. Rumors of the iPhone 5S at the same time are also bubbling around, so it will definitely look like a clash of the titans come early 2013.
