I was told this. Comcast is pleased to announce that we will begin to deploy new XFINITY Internet speeds at no additional charge for our Blast! and Extreme 105 customers in the Northeast Division on April 1, 2014. Blast! speeds will be increased from 50/10 Mbps to 105/10 Mbps. Extreme 105 speeds will be increased from 105/20 Mbps to 150/20 Mbps and will be renamed to Extreme 150". Customers will receive faster speeds for the same price they are currently paying. However, it is not yet available on your Central market. but I was ordered it by a Comcast Sale department
even tho I have Extreme 105 already I was told Extreme 150 is not a free upgrade so when they come on Sunday something better fucking happen,
