As per various rumors the Galaxy Note 6 might see the light of the day as early as June. If that happens, chances are less that it will be packed with the Snapdragon 823. While reports state that Qualcomm is gearing up to release the Snapdragon 823, it will be sometime before the processor is actually introduced into the market.
Thus, there is the possibility that the Galaxy Note 6 is released before the Qualcomm Snapdragon 823 becomes available in the market.
The device will be waterproof and dust resistant and it will have IP68 certification in these departments. It will be waterproof up to a depth of 1.5m for 30 minutes. A fair amount of battery will be required to run the powerful device and thus chances are high that the device will be loaded with a 3500-4000mAH battery.
As for the OS, Android 6.0.1 Marshmallow seems to be the logical choice. However, it should be remembered that Google has already made an announcement for the next Android OS- Android N and various rumors indicate that the Note 6 might be loaded with this latest OS from Google.
The OS will be more advanced and even smoother than Android Marshmallow.
Stay tuned for more update on Samsung Galaxy Note 6.
