The photos only show the new 7" KFHD but not the new 8.9" model, and they support past rumors that the new tablets would have "a more angular design with a flat slope out to the edges instead of a curved slope, and corners that aren’t as rounded."
The front also reveals that the new 7" tablet has a radically different appearance.
It's not clear to me whether this tablet is Soho or Thor (respectively the new Kindle Fire or the new KFHD), but the original source is saying that this is the new KFHD. The photos come from Boy Genius Report, and their rumors have proven reliable in the past.
The 7" KFHD shown above and below is expected to be running Android 4.2.2 on a 2.15GHz Qualcomm Snapdragon CPU. It's going to come with a 1900x1200 resolution screen, a minimum of 16GB of storage, 2GB of RAM, Wifi, the front-facing camera shown in the photo above, and optional cellular connectivity.
As you can see, the new tablet is keeping the speakers on the back, and like its predecessor it does not have a microSD card slot. This tablet is predicted to be shipping sometime in the next month or so, but the larger 8.9" KFHD might not get out the door until November.
There's no word on price, but given the more expensive CPU and screen I think the price could go up from the current $199 for the 7" KFHD.
