Looking only at capacity, it will definitely be cheaper to provide unlimited plans but even if that was the only factor, there isn't much of an incentive for carriers to change how they charge for bandwidth.

In all likelihood prices will go up as 5G requires a massive infrastructure deployment of very expensive hardware, spectrum licensing, and they'll have to pay to transmit and receive that data to the internet. All of those additional costs will be passed on to customers.
