Are 3.9 GB Updates the New Norm?

I had some free time tonight so I decided to play a little Battlefield 3. I go to BattleLog and it tells me I have to update the game first to play. So I start the update and notice that its a 3.9 GB download! Wow.

I can’t imagine why the update needs to be that large. I think I’m having to download the whole game again just to update it. Thank goodness I’m not on a metered internet connection.

Dice says the reason that the download is because “it contains most of the content for Back to Karkand”.

I guess the download isn’t so bad after all.
