said by FFH5:Only if cap remains. I doubt it will. This will be a premium service, like a business acct, and will most likely not have a cap. It will also be priced that way.
DONT' COUNT ON THAT, You have seemed to forget comcast has business class service and that is there ONLY service that is not capped, currently Business class cost $370 per month for 100/10 mbps unthrottled/uncapped. So you can bet your ass 305 mbps for $300 (as its been announced it will cost) will be capped and maybe throttled, If not current Business class customers would switch over in a heart beat, now they may raise the cap ( to 300-400 GB) but it will be there !
