It is a shame because we really need the 111 for Battle of Britain scenarios, but i don't think it will be added for a while because it will offer pretty much nothing in the MA (apart from the cool factor).
They could add two versions though, the bomber and a perked, armed, paratroop version - that would give it a niche role in AH and make it worthwhile.
A Junkers JU-188 would be a better Arena bomber i think.
