I would be very shocked if prices when up.
Unless they are targeting a niche market, I expect prices will drop. in other words, what percentage of the market are they targeting? If it is just people who do not have access, then no it will not. If they are targeting people with crappy internet, then the price of crappy internet will probably go down to stay competitive.
In addition it depends on quality. If you are a twitch game player, you are willing to pay for whomever provides the least lag time.
