It won't get faster, your connection can go up to 8MB, but you need to look at reality here. You lose speed because you need to connect to the main stream of wires underground, which can be miles away. You also lose speed if your neighbours also use BT, as they are accessing the same line as you, and thus you are sharing their speed. BT also has to go through your phone line, which can slow your connection down.
All these factors can slow your connection down. It all depends on where you live, I wouldn't expect it to get faster, your Internet speed won't be faster by some magical force, it's real wires underground that do all the work
