You know that bit during the middle of the WWDC keynote where Apple asks a few developers to demo their apps? The bit where everyone in the audience checks Twitter, and the people at home use the bathroom? This was two hours of that.
There are “Family Guy” jokes that end quicker than this keynote did. This was only succinct if measured on a geological time scale. There are archaeologists in the process of digging up the remains of the beginning of the keynote to study historical life. While this was theoretically the PlayStation 4 announcement, they failed to show any hardware (aside from the controller), didn’t offer a price, and vaguely gestured at a release date. There are Android tablet announcements at CES which have more details than this did.
