They should increase exponentially over say a 5 year period. Anyone can not see a sign or accidentally overstay a meter now and then, starting with a “Hey jackass” amount of money that to most people would merely be an annoyance but escalate relatively quickly.
My prediction is that sony and microsoft will have benchmarks 3rd party devices have to hit in order to buy a “PS6 Compatable” logo for their product. So you can buy a Msi Claw 3 or whatever, sign into the PSN and shop the sony catalogue.
