It's not KitKat, but you can now get a ROM based on Android 4.3.1 for your Bionic here:
CyanogenMod Downloads
You will also need the 10.3 compatible version of Google Apps:
Google Apps - CyanogenMod
There is also a "Milestone" version of CM 11, based on KitKat so with luck we'll see a stable version of that ROM soon. Keep your fingers crossed (I know I am).
