The entire pad can also be "clicked" for an additional input button."

We'll begin with the specs. And before we go any further, know that these are current specs for a PS4 development kit, not the final retail console itself. So while the general gist of the things you see here may be similar to what makes it into the actual commercial hardware, there's every chance some—if not all of it—changes, if only slightly.
That being the case, here's what we know is inside PS4 development kits—model # DVKT-KS000K—as of January 2013. As you'll see, some things have changed since earlier kits became available in March 2012.
