Both of those statements ( caps and Overages) are what you will see in the next wave of Verizon commercial adds when Comcast ( and you know they will) start running adds that there the fastest internet provider.
Also Verizon will just kick it up a few nickels (to 320 mbps) a month or so after the comcast roll out is up and complain to the FCC if Comcast tries to run adds that there the fastest.
I'd hope so, but ISP competition is barely perceptible. Also Verizon probably won't say anything so that it can leave open the possibility of metering in the future
