For the second week in a row, the PlayStation Store update will be delayed. Sony usual schedules the update to take place at 2:00pm Pacific Time, but the company has acknowledged on Twitter that the update "may be a few hours late today in fully publishing." Last week's delay was caused by "technical issues," so I'm assuming it's the same thing this week.
Update: PlayStation Store may be a few hours late today in fully publishing. We'll keep you posted!

Once the store is fully updated, PlayStation Plus owners can expect to see Thomas Was Alone (PS3, Vita) and Unit 13 (Vita) available for download for free. Metal Gear Solid V: Ground Zeroes, Final Fantasy X|X-2 HD Remaster and Luftrausers have also been released today and should be available for purchase once the update is fully published.
