BF4 beta can't connect.

this same thing happen to me deff wont get the game if this **bleep** dont let me play the beta no more

Will my stats, rank and all that carry over to the game after its release?

In the past Betas, EXP, unlocks and awards all reset.  

I thought the beta was open until the full game was released?

The beta was not taken down without notice. These were the places I could find it in 1 minute:
