Do you mean is Eastenders still being made, or is it still being shown in BBC America?
It's not a show that I watch, but I do know that it is still being made as I am from Northern Ireland. New episodes are aired 4 nights a week on BBC One in the UK and last night's episode was episode 5160. I don't know how far you guys are behind with episodes in the U.S. and I don't know about the airings on BBC America, but if the show is popular on that channel, it should return. I also think the new episodes are uploaded on youtube not long after they air so you can try there.
Hope this helps
