The Battlefield 3 Beta has been out for three days now, and I'm going to say my thoughts now. Operation Metro, while being the obvious weaker map compared to Caspian Border, is still a fun map. This is a rather small map, but once you go into the subway station, it's loads of fun. There are many small tunnels and routes you can use for flanking, and a long tunnel where the subways are. The one thing about this map is that there are not many destructible areas. The most you can do is break some wood panels and knock the face off some walls. I think that they shouldn't have picked this map for a beta, instead a map with vehicles, fully destructible environments, and more open spaces.
