It was confirmed that the Destiny Beta release date will be stated during E3! Can't wait! I've held onto my pre-order copy for a month now, and the closer the beta gets the more anxious I become.
I haven't pre-ordered my games yet, I plan to do so after E3 so I can do it all in one go, that and if special editions were to be announced.
I was lucky enough for someone gave my a Destiny Beta code, than there's my friend who actually pre-ordered the game but never got a code.
Destiny is planned to have the beta in July, two months before the game comes out in September. Guessing it's July for both Xbox One/Xbox 360 and PS4/PS3, I'm guessing it'll be out on PS3/PS4 on July 1st, 8th or 15th and on Xbox One/360 on July 15th, 22nd or 29th as Sony consoles get the beta 2 weeks early and Beta's usually fall on Tuesdays. IF it was any day, it'd have to be 7th of July.
