1st October, we will see the start of Battlefield 4′s open beta. Xbox 360, PS3, and PC, will all be able to access the Beta on this date. Battlefield 3 premium owners, were offered an “exclusive” Battlefield 4 beta. However, it seems EA haven’t delivered on that promise. As you should all remember, Battlefield 3 had an open beta for the same platforms.
The game itself will be released current-generation consoles on the 29th October, and then you can expect it to be released on next gen.
