Default Updated samsung push /kitkat questions

Anyone else notice the updated sammy push? These tend to happen prior to fw updates. Mine updated 48 hrs ago, i377m (rogers). Kitkat rumoured this month for s4 cdn. With announcement of it pushing to note devices, id imagine kitkat for s4 is next. Now for my question. Looking for a link or info on update process. Would like to keep root, currently on 4.3 rooted, using supersu pro and wanam to fake official. We able to simply pull update ota? I always used odin to flash, but since knox with 4.3,not sure. My knox is 0x0, so looking for a knox safe update process, if one even exists yet.
