I noticed someone's card said June 7th but mine says June 9th?
Mine is still being forwarded from California, so I can't answer this. I do believe though, that these kinds of things are now being posted in the sticky thread at the top of the forum titled PCE Questions, Comments, Issues here! So someone in there can probably answer you.
The card says June 9th - June 17th. I believe there is a presale the 7th and 8th.
