Google is graciously holding back on Android 5.0 so that manufacturers can update current models to Android 4.2 and not have their phones 2 updates behind. As a result, new models getting released in the summer to perhaps as late as the middle of the fourth quarter, will probably be powered by Android 4.3. Heck, it's even possible that we might not see Android 5.0 until early next year.
The model number on the AnTuTu test was GT-N7200. That is right in line with the GT-N7000 seen on the original Samsung GALAXY Note and the GT-N7100 on the Samsung GALAXY Note II. In addition, a picture alleged to have been taken by the Samsung Galaxy Note 3 had the GT-N7200 model number listed on the EXIF data.
Usually when we start seeing a model number listed on things like EXIF data and Benchmark tests, it means that we are getting closer to the unveiling of a new device. Recently Samsung executive J.K. Shin said that we would see a 5.9 inch Samsung Galaxy Note 3 unveiled this September at IFA Berlin. EXIF data and benchmark tests can be faked though, so let's keep an open mind about the device for now.
