The slo-mo clues, spotted by 9to5Mac, come from code hidden in iOS 7, the next generation of Apple software for the iPhone, iPad and iPod touch. Codenamed Mogul, the slow-motion feature would allow for video recorded at 120 frames per second, allowing you to play back the results at standard speeds and create a ssssllloooowwwed-doooowwwwnnn effect that would make John Woo proud.
Although you can get a beta version of iOS 7 on the iPhone 5 and other present models, the current camera lacks the required hardware to film in slo-mo. So we'll have to wait at least until the next iPhone turns up with iOS 7 later in the year to try slow-motion video -- and even then there's no guarantee the feature will actually be turned on.
Apple is expected to announce not one but two iPhones this time around: the usual iPhone update, set to be called the iPhone 5S, and a cheaper plastic iPhone rumoured to be called the iPhone Light.
The regular Samsung Galaxy S4 offers an assortment of camera modes including slo-mo and an option to capture animated GIFs -- check out our in-depth guide to the S4's camera -- while the HTC One offers the clever Zoe mode.
