So i sold my xbox a long time ago, and when i had it i was obsessed with bf3,

so now im planning to buy it for the pc, however, what is this battlefield premium edition? whats included?

also do i need to buy premium and normal copy or just premium if i want what comes with premium?

also, why did it say pre order? is it some expansion pack available soon or something?

theres a battlefield 3 premium edition
