Units sold through would be my guess. This was at the end of the montage right before Layden came out on stage and said PS4 is the fastest selling console of all time.
We dont know these number until which date. I think it should be until first/second week of november so it will complete 1 year. Sony said fastest selling console of all time, so what was the highest numbers for first year before we can guess PS4 is above that.
GAMING is not about spending hours to pass/waste our time just for fun,
its a Feeling/Experience about a VIRTUAL WORLD we can never be in real, and realizing some of our dreams (also creating new ones).
So, Feel Emotions, Experience Adventure/Action, Challenge Game, Solve puzzles and Have fun.
PlayStation is about all-round "New experiences" using new IP's to provide great diversity for everyone.
Xbox is always about Online and Shooting.
Nintendo is always about Fun games and milking IP's.
