[CenturyTel] any chance of speeds like this?

Are there any chances of speeds like this. I signup with no contract just in case something like this came along. Thinking of making a switch. 10 MBPS around the same price of 50MBPS. They better offer me at the very least a 40 MBPS connection at a very attractive price or i am gone. http://www.dslreports.com/shownews/Cox-Boosts-Speeds-Offers-150-Mbps-122981
