I havent really been into game systems in w while but the whole anti play/piracy stuff is just silly anymore. Its suicide for them to try to lock things down, someone will break it within days of it being released just on the basic principle that having a locked down system they paid for is silly. One day these companies will realize that if they actually sold games, cd's, movies, etc for a reasonable price, people would buy them without the bother of hacking around to get them.
Remember the Sony debacle? They spent 100M and said they had the systems licked for being able to rip their new cds. Some dude in Europe defeated it in about 5mins with a sharpie marker. 100 MILLION invested defeated by a $2 sharpie.
Anywho, ps4 vs new xbox, I think it will continue to be silo'd between users, with some having both and folks just getting into gaming having a hellova decision to make. They will both offer something the other doesnt is my guess and that alone will likely make the decision for most folks.
