According to USA today. Both versions of the new K3 are sold out and deliveries are now beyond 8/27 for new orders. Yesterday when I looked it was 9/4 for preorders now.

Similar to the Nook launch. When I bought my K2 it was for Christmas and I had originally wanted the Nook, but preorders had swamped capacity and new orders were delayed until like late Jan. That fact and the fact that playing with the Nook in a B&N showed it didn't have all the kinks out, prompted me to buy a K2!!
