My prediction...
• Water+Dust Proof
• 2K OLED Display
• 32GB base storage
• Quad core CPU @ 2.0 GHZ
• 16MP Dual Camera with 6th element lense and bigger sensor
• Stereo speakers/microphone
• Ultra thin design with glass back
• Liquid metal frame/body
... I guess that's it and will truly be the biggest jump ever for the iPhone. I don't think there's anything more that they can add until the 7S.
