If they do that it will be met with anger and despair. Out of that there will be those who accept it and those who reject it. Plenty of confidence will be lost in Sony and MS will sell more this gen. The backlash will cripple PS4 sales and further damage Sony as a whole. One of the main reasons I like Sony this gen is their attract consumers through compelling optional content approach.
If they do this than what of the PS3 and the Vita? No one will move to the PS4. The concept doesn't make sense and if they restrict online play for those consoles then you can bet the lines at Gamestop to trade in those consoles will be out the door.
I personally would demand refund on the PS plus I have, start a petition and flood Sony with distressed consumer calls.
I hope if the big publishers are pushing MS and Sony in this route that Sony has the balls to look at them and say "Oh you want to put in place a no used game system? Well we have one. It's called digital only" and that be that.
Before the PS3 everyone was nice to me :(
