With the Mobile World Congress (MWC) hitting Barcelona, Spain at the beginning of March, it’s that time of year when top Android phone makers are preparing the new generation of Android phones for release. While nothing’s official yet, there are plenty of leaks from usually reliable sources that enable us to paint a picture of the newest Android-powered phones. Perhaps even more importantly, we can get an idea of what this means to mobile gaming and marketing in general.

The leading Android phone producers that are expected to launch new phones in the next few months include Samsung, HTC, LG, and Sony. All are expected to produce new versions of their flagship phones, which will of course be at the premium end of the price range. While these phones may not be responsible for the largest sales numbers in the year ahead among Android phones, they do define the top end — which in a couple of years will be the middle to lower end of phones. For game developers, it’s important to keep an eye on what’s happening at the cutting edge of technology to know what sort of features you can expect to see as widespread among Android phones in a year or two.
