[PS4] Confused - 3 Different Options of BF4 on Play Station Store

Hi guys,

I have just recently purchased a PS4, and I am also aiming to purchase Battlefield 4 (I know its an old game) from the Play Station Store. I have also read many posts and articles about how you must get a standard edition or deluxe edition first, then purchase a premium version in order to get many benefits such as expansion packs. 

I went onto Play Station Store and started looking for the correct product of Battlefield 4 to purchase. However, I stumbled across THREE options for Battlefield 4 PS4. 

1. Battlefield 4 Premium Edition  (Premium2 Image)

2. Battlefield 4 Premium (Premium1 Image)

3. Battlefield 4 (Standard Image) 

- So I see that #1 and #3 are the same size at 31.6 GB. Does that mean both versions include the base game + multiplayer? (Does #1 still have the expansion packs?)

- All three of them have different prices, #3 at around $30.00 USD, #2 at $50.00 USD and #1 at around $60.00 USD. If the size of #1 and #3 are the same, why are their prices different?

In conclusion, I have seen people already purchased standard but they then have to get premium to get the other expansion packs. I personally want the game with all the expansion packs and not much else. I would like to know the differences in these three versions because the website was pretty vague and I would also like to hear some advice for which one to buy since I have NOT yet purchased any.
