Do you think 4.4 is going to break root again?

I know that 4.3 messed up root, so I'm wondering if 4.4 will do the same. What do you think?

i just noticed yesterday that apparently ever since I flashed 4.3 on my Nexus 7, it doesn't have root, even though it has SuperSU installed. It also doesn't have TWRP anymore either, but I feel like that's indicative of other problems with my tablet because I've lost custom recoveries before, so I'll just have to reflash before 4.4 comes out.

Anyway, what're the chances that it messes up root, and how long do you think it'll take chainfire/koush/etc. to fix it?
