WOW! 1)What is the source of this image? 2)How recent is it?

Here is some speculation based on what I can see in the image:

3)-Perferated areas on bottom half of device on either side appears to be location of microphone and speaker. This may be a better device for VOIP functions or perhaps actually includes a phone.
4)-Antenna (or is that a stylus sticking out?) in top left seems to indicate cellular voice and/or cellular data connectivity
5)-The 3 buttons beneath the rocker appear to serve a double function as a scroll area. Should be very nice for web browsing.
6)-Appears to be a bit bigger than the 770 due to increased area on right side of screen. Would have been nice if they had added a few general purpose buttons on that side as long as they are are increasing the width.
7)-What is the silver thing in bottom left of screen
8)-The "hump" for the USB, headphone and power connector appears to be gone. Yay!
