During Sony's PlayStation event yesterday in New York City, the company officially announced the PlayStation 4, but they still left a lot covered up, namely the actual console. Sure, they showed off the new DualShock 4 controller, as well as a few new games coming to the PS4, but the gaming console itself was MIA. It turns out that the console is actually still under development, according to Sony CEO Jack Tretton.
In an interview with AllThingsD, Tretton explained that there were a couple of reasons why Sony didn't show off the new console at yesterday's event. First, Tretton explains that the console box itself really isn't all that important anyway, since "it’s behind a cabinet or on a shelf somewhere and you spend all your time looking at the screen." Tretton has a point, though. After all, the box itself doesn't really matter all that much.
He also noted that the console is still under development "in terms of final specs and design," so while they may have a PS4 console built and able to play games (as we saw yesterday during the event), it seems that Sony is still working on adding final touches to the console, and from the looks of it, the PS4 isn't quite ready for mass production just yet.
Tretton's answer differentiates just slightly to the answer that Sony's Worldwide Studio president Shuhei Yoshida gave, in which he says that Sony simply didn't want to unveil everything during that one event, and instead want to spread out announcements, which means we could hear more about the PlayStation 4 come E3 in June.
