As someone with both consoles pre-ordered, I can tell you that (unless some major differences reside) this feature would definitely push me to choose XB1 versions of cross-platform games over the PS4 version (and perhaps PC) anytime I'm deciding which to buy.
As I understand it, I can play a title I own, either independently or with one "family" member who has access to my library (no, not all ten of those members) at once.
From a MS/Sony perspective, I can see the incentive. Sure, some titles (like short single-player games) would lose a sale when I could just borrow my friends copy rather than buying it myself. However, they'd be gaining a sale in that they're adding tangible value to the XB1 version over the PS4/PC version, so it'd make me and my "family" members much more likely to purchase XB1 cross-platform titles.
Additionally, if I'm home from work and decide to try out a title from someone else's shared library, I am much more likely to make an impulse purchase when I've already downloaded everything and am seconds away from owning my own copy.
I know everyone is waiting for the other shoe to drop, and it may, but I think the option we're reading about today is viable.
