Any news on a successor to the U2 USB miner, the U3?

Soon, I guess. The U3 will be using the new BM1382 chip.
Probably will hash around the hr of 1 BM1382 (which is 15GH/s)?
I don't think so, the Chip needs by 15 GH/s to much power, but I think 5 - 8 GH/s with one USB miner (One Chip) are possible!?
