My guess is that the TK4 will have a 7 inch screen to position it against the Color Nook at a lower price. It will be 3G & WiFi. $169
The BK4 will be pretty much the KSO but might come in colors. WiFi only. $114
The kPad will be a larger Color Nook. $359
If I am wrong, my account was hacked & this was posted by someone else.
