I mean yeah there are a lot of cool features and I am sure the system will be amazing, but what about the PS3? Sony did this last time when they released the PS3 when the PS2 was still a solid system. Now they are going to successfully divide their portion of the gaming industry to people who are PS3 users and people who are PS4 users.
I love PS, but what is the point on getting a PS4 when I have a PS3 with 40+ games? I can't use them on the PS4 because it isn't reverse compatible. Come on Sony, didn't you guys learn last time when you pulled this crap?
