For those planning to buy it from PSN like myself note that the store won't be available before 7pm ET. That is if they keep their word, as they usually don't. Last time this happened they updated the store next day. Why are they doing this on Tuesdays is beyond me, but whatever, Sony is Sony. Might just pick up a physical copy, even though its a hassle switching around memory cards for a 400Mb game.
+ Paul Sullivan on June 24th, 2013 at 7:43 am said: Our teams worked hard over the weekend to ensure that this update can be released later tonight (night of June 24). This will allow you to hop into the store tonight ahead of tomorrow’s store update post, and pick up your purchases prior to the Tuesday downtime. Since this is an early update, be sure to take advantage of any current sales now, while you can. We recognize that Tuesdays aren’t the best day for these, but it was required. As noted, we did our best to ease the pain that this may cause.
