It's a safe bet to say the Galaxy Note III will be the star of the September 4th event that Samsung is holding before the IFA, but for anyone needing another confirmation that the next Note is on its way to being official really soon, the references to the Galaxy Note III by name in Samsung's SideSync documentation should be fodder enough.
In the instructions for SideSync, an app which enables users to connect and share data between their Galaxy phone and a computer, on Samsung's website, the Note III is mentioned quite a few times and will apparently come pre-loaded on the device. Of course, instruction documents never list the specs of a device so we're still going on rumors in that regard, but again, it's a good confirmation of the fact that Samsung's next big thing will soon be hitting the market.
The Galaxy Note III is expected to sport a 1080p Super AMOLED screen anywhere between 5.7 to 6-inches in size, an octa-core Exynos 5420 or quad-core Snapdragon 800 processor depending on market, 3GB of RAM, 13-megapixel camera with optical image stabilization, LTE-A connectivity, and Android 4.3 Jelly Bean. As always, we can expect to see some new software features, especially ones that make use of the included S Pen stylus.
