I am unclear still if pre-order accounts gain access to the closed betas coming up soon? If so I need to go and get my copy pre-ordered soon instead of getting a box copy.

Yes.

To be clear all pre orders are supposed to have beta access. However, due to someone fumbling the ball somewhere, if you pre order from somewhere like gamestop or amazon, then you'll have to wait for you're beta code since it doesn't seem to be available yet.

If you pre order from En Masse, you account will automatically be cleared for access.
