They will simply offer a new tier with the "Current Gen" Games! Something like they did with NSO+ Expansion Pack which has GBA games - extremely old but is almost equal to price of PS+ Essential! It will still demarcates Sub and online only prices so the 1800/$20 per annum price will remain (or this tier might go up like all other goods and services on this economy but it'll remain separate and cheaper compared to others I feel)
