Remember, the new sheriff is focusing on families, not as much on the thrill seekers and enthusiasts. It does not take a psychic or even the ever so intuitive Terpy to interpret what that means. I would not expect another major steel going in soon, although I would possibly see a mid size family coaster in the next few years.
As far as AZ goes, I think they have gotten a good start on the revamp of that area with what has been mentioned above. There is only so much money to repar/fix/replace areas of the park. SOB aside, at this point they have Invertigo and FD taken care of already. With that already done maybe we will see a nice repaint and light package added to DT, possibly pavers, and maybe rest rooms and shops painted. Just those items would spruce that area up. Look at what that did for CM and Rivertown the last few years. The water tower does not do anything for me and could be removed. A mini stage in that area instead would be nice for an evening show/DJ/karaoke.
