I don't know, my Comcast offerings got substantially better over the last few years before I moved, going from 6/1Mbps to about 20/5, and I could have had well beyond 100Mbps down by the end if I felt like paying for it.
I'm quite aware in both cases, as I have FiOS now, and Comcast was the only game in town at my old place.
My point, which you seem to have missed, or at least not addressed, is that Comcast did substantially improve their offering while Verizon was rolling out FiOS, even though they remained the only real broadband provider in my area.
