If you love Xperia Z for its water resistant capability, this Sony Xperia ZR with IP55 and IP58 rating will push it even further. You can now submerge it into fresh water (up to 5 feet) and take video or pictures without any issues. Check out the videos.
I have no official release yet but according to Mashable, it will be available in Q2 2013. There is no price range yet. The specs is the same as Xperia Z except for the underwater capability.
Here is another video to show more about the Xperia ZR.
Hopefully, people will not start to abuse the usage in the pool.
