Bump, also wondering this. I just pre-ordered it expecting to play it after the Superman premiere that I just saw (good movie and all, but this was really going to be the star of the show for me) but it's still 1 hour and 40 minutes till midnight, so we shall certainly see soon.
EDIT: Also, I'm USA central time, which is often the time they go by, so if anyone is still wondering, give it another hour and a half (plus a couple minutes of course, after all it has to be AFTER 11:59 PM CST) and try again.
I would think that the digital release for The Last of Us would be available by midday. The store operates by Pacific Standard Time, though. If the game will be published at Midnight on the West coast, that would mean everyone in the Central time zone should look for the game's availability at 2 AM this Friday. At this time, it is still Thursday the 13th. *insert Friday the 13th theme music*
It's 11:53 here. If it doesn't become available for download then, I'll just assume it means I'll have to wait an extra 2 hours.
EDIT: Didn't unlock yet. Just keeps downloading this **bleep** static theme ;_;
