The pictures means she will be doing some dancing. That is beyond speculation. She is not going to post 3 pictures unless she is sending a message. The message is - "I heard you."
Now, as for the music itself, she knows this is really her last shot at it. I believe she has gotten the message that she has to aim this one at the largest audience possible. Therefore, I think she will hold a lot closer to the pop arena, with some very dancable numbers in it. We have heard rumors about this already, and I believe they are true (or at least good guesses). My one hope is that she keeps the album lively - a good portion of faster and catchier tunes.
