Sony Z Series Out Now!

. . . in the US. http://www.sonystyle.com/webapp/wcs/stores/servlet/ProductDisplay?catalo.... Wonder when of the world will get this? Based on the pricing, the Z sits between the W and the X series which doesn't makes any sense because Z comes after X but they ran out of letters. Also, seems like the US X-series is onto their 5th G but the rest is only on 3rd G???
