Predictions for the new season?

Ya know I am not totally sure how this is going to go but both me and my husband can't wait, it seems way too long since last season I really don't remember everything, I know the big things though. I am not sure Mackey is going to go down, inevitably it will be the end, but I wonder if he will get a retirement package or transfered to a less vital role to finish out is 20. I am still a little ticked that they got rid of the one lady captain she was about the only one doing any good, but thats how hollywood keeps our interest. I don't remember what all they are but mackey has a lot of strings he is pulling and I almost think he may pull them off, but can't be for sure. I think the last season ended too prematurely it left TOO many questions unanswered and things unresolved. Can't wait to see though.
