lol. Bungie never made a contract with you or anyone else regarding the beta.Peck peck peck and ignore the larger concept.
I'll say it this way. It's like EA making TF multiplat after taking the money for Xbox exclusivity. Exclusive access to the beta was the incentive to pony up the bucks.
I'll ask again. Why pre-order on psn for beta access if it's going to be given away for free anyway? Why should I trust this won't happen again with other such offers? PEACE.
You don't pre-order anything from services where you can't cancel your order unless you want to pre-load it and that's it. That's the incentive, not the beta access.
