Comcast Prepping A 305 Mbps Tier?

It looks like another ISP might be jumping on the 300Mbps bandwagon. I wonder if Comcast is going to have bandwidth caps in place on its new service? There's no hard timeline on the offering yet, but clearly Comcast wants to keep pace on the PR front, Smit making sure employees knew they'll offer 305 Mbps just to make sure they one-up Verizon. One problem is that Comcast isn't really utilizing upstream channel bonding to its full capability yet, so it will be interesting to see just how close to 65 Mbps Comcast can get on the upstream side of the bar. Comcast upstream bonding tests last year were able to achieve 75-100 Mbps.
