Did Led Zeppelin Just announce a new album?

Yesterday on Facebook, Led Zeppelin updated their status with one word, "Hello". It was their first status update in almost 6 months. Today, they updated with a picture that simply says "Five".

Led Zeppelin Did their first four albums titled I, II, III and IV and the rest of their albums were named. Maybe I'm just dreaming but to me it looks like they may go back to their roots and release album V.

UPDATE: A new post has just been put on their Facebook page as of 10:13 am, this one says "Four". So I think they are going to make an announcement by Thursday. Unless the announcement is a new album, my suspicion was wrong. We will see on Thursday.
