@my_pain: You only get two free game now and Xbox is still giving 4. Now that they have sold 100 million systems, they don't care if you subscribe to PS+ or not. They already won big time! So at this point, they could just stop giving free games entirely.
Every system from now on has to be backward compatible. If purchases are now mostly digital, your games need to be able to work with future versions of the system. Otherwise you have to rebuy the game over and over.
