Emily Rogers updated today with these two tid-bits, reiterating it's below an XB1 in power, and from what she's heard the battery life is not great (worse than 3DS?). 

Also no camera/mic on the main unit which seems kinda weird. The "dock" has 2 USB 2.0 ports and 1 USB 3.0. 

Nintendo is "ahead" of schedule on a March launch according to her, probably means there will be a good amount of software. 

Take it for whatever it's worth. I have no idea if she's right or wrong. This is her rundown:

Here is what you can expect from the final retail product:

• Custom Nvidia GPU chip
• Region Free (No region lock)  <– Confirmed this.
• Six inch (6.2 inch?) multi-touch screen (Heard nothing about a stylus)
• The touchscreen has 720p resolution. <— 100% Confirmed.
• 32GB of built-in internal storage
• SD card support
• Supports USB 2.0 and 3.0
• The dock has two 2.0 usb ports and one 3.0 usb port.
• The device is around 14 – 15 mm in thickness.
• The right analogue stick will be below the face buttons.
• Camera and microphone are not built into the NX portable device.
• Cooling is still a little noisy
• Detachable controllers (motion controls and next-gen vibration technology) <– Everything Laura Kate Dale said in her article was correct.
• Share / Social button that Laura Kate Dale posted is true.
• There are at least two shoulder buttons. I haven’t heard anything yet about triggers.
• Battery Life — Ehhh not great. I haven’t heard an exact number of hours, but it doesn’t sound great.
• Below PS4 and XB1 in raw power.
• Supports Unreal Engine 4 and Unity Engine.

Note: I am not saying that NX won’t have a mic or camera. I am saying that the camera and mic aren’t built inside of the NX portable device.

Again, she does not state her sources. She also mentions that they are just rumours that should be taken with a grain of salt, so why listen to what she's saying at all?

How would she know the battery life? That sounds like something only people really close to development would know.

If what she's saying is true she must know someone with a dev kit. 

why would she state her sources? wouldnt that risk getting them in trouble?

Because for all we know some guy off the street could have told her this. It allows us to determine whether or not she is getting information from an insider.

She doesnt know if the controller has a stylus or not, but she knows the battery life?

I hope it's slightly smaller than stated here, don't really care if it has a mic or camera. Would like information on the dock though, other than it having 2 usb ports... does it boost power? Or is it nothing more than a glorified charging cradle with hdmi output.

She mentions the fan cooling being loud ... Nintendo couldn't be making a portable that has a fan in it .... could they?

That would be interesting if its in the final build. The only tablet I know of with a fan in it is the Microsoft Surface.

Wouldn't no camera mean no augmented reality games though? That part seems like an odd design choice.
