I got an 8GB with my dirt cheap PSTV. Sony / BB was practically giving those things away a few weeks ago.
I wouldn't trust some cheap card and I've seen others say they went for New official cards. So slight possibility. More likely it's Vita though.
At this rate my email will file for a restraining order against me. I got my eye on you! *stares intently on email*
Codes are going out later tonight, so take a break from watching your email! Didn't want to send them too soon since they won't work until the store populates with the new content (including SN5) tomorrow afternoon.
Sending them later should limit the "dude, my code doesn't work" from the people that don't read the accompanying email that explains when it's live.
