NX1 Feature Request

I realize it is too late for NX1 feature request, but here is what I want from NX1:

• Mag alloy construction (every other top tier camera uses it)
• New and improved sensor
• Eye detect AF (focus on nearest eye) -> this is very handy, especially with large aperture lenses.
• AF button (ability to turn off AF with shutter press, like all decent SLR cameras have)
• OLED Viewfinder, large
• Better on sensor PDAF/CAF
• Allow manual focus at points other then center for non-AF lenses.
• Put the USB port so it isn't in the handgrip (can use NX30 while charging via USB, but it is difficult to hold with USB/HDMI cable sticking out of grip)
• Longer than 4 minute bulb exposure and disable of dark frame subtraction for bulb
• Use timer delay for bracketing shots (avoids shake) or allow bracketing remote viewfinder app
• Battery Grip
• Faster buffer clearing
• Larger buffer (at least twice as large as NX30)
• 4k video (I don't care about this feature, but some will)

I was keeping a mental list, I am sure I will think of something else later.
