It's allowing us time to clean up our link profile and then may be after 3-6 months it will run again.

I agree with this observation, but I think there are several things going on here. In addition to allowing time for links to be taken off, Google is most likely also looking at rate of acquisition of new links... and it will be much easier to do because Google will have a well-defined group of sites to watch.
