I hope they give the new flash head the same range of rotation as the 600EX-RT. The head of the 430EX has a limited range of rotation. When holding the camera in vertical position, the head will only rotate 90 degrees straight upward. This means you can't angle it a bit backwards as you can with the 600EX-RT. Likewise, when holding the camera in horizontal position, you can only turn the flash head 90 degrees to the right (although you can turn it 180 degrees to the left). This makes the 430EX much less useful for me.
