Will the Sony Z4 have Sony's IMX 230 sensing technology?

[AC Question]

Sony recently announced its IMX 230 camera image sensors, which allow the taking of still HD images from high-speed motion (say, sports or recreational activity). The current 21-MP camera has been there since the first Xperia Z, so it's time for an upgrade, though it already beats both Samsung and Apple in that area (no surprise here--Sony supplies both those companies). Also, it'd be great to know if the Z4 will sport hi-res audio. Could it be the Xperia Walkman?
