Question about lowlight

I am getting my camera in a couple of days so I will find this out soon enough, but I am curious to see what others have to say about it at the moment.
When I first heard about the camera people were saying it was awesome but it wasn't great in lowlight. That was a bummer for me a little bit, because I love to have that flexibility to really see in darker areas. However, a friend of mine pointed something out to me not long ago that made me think. If we are getting a latitude of 13 stops going up to an ASA of 1600 then how much could you push this footage in post? Just how dark can it be and still ultimately pull out usable footage? I am coming from a 5D MKIII which was amazing in low light. So that might be a good jumping off point for comparison.
Love to hear some opinions.
