According to the Battlefield wiki, Armored Kill has only been released on PS3 for Premium members so far. Premium members will get it on PC on the 11th and non-Premium players can get it on the 25th.
it's on the xbox too unless it's cross platform since it showed servers for it.
Premium costs the same as buying all the map pack seperately or less but you get the maps like 2 weeks before they go on sale i think and a few other goodies IIRC
