While many of you are familiar with this "PS4" thing that Sony is bringing to market, there is the off-chance that someone may not have heard of it. The first official PS4 commercial for America is titled "Perfect Day," and is largely reminiscent of the "Greatness Awaits" promo that ran on YouTube earlier this summer. The main difference? It's a musical--as Sony is wont to do. It's also, notably, a very different approach than Microsoft took with its first Xbox One ad.
