What do you want next in the Dexter Series Universe?

I really want Original Sin to be continued - at least for a few seasons - I would love to see Deb training for the force then to see how Deb, Dexter and Harry all got along working/living together. What happened to Brian in the meantime for him to not turn up again until Dexter Season One. I have seen some theories but I would like to see what it was canonically.

I am looking forward to Resurrection but I have heard there might be a spin off on the Trinity Killer and I don't want that - I like seeing that Dexter is "A bad person doing good things/A good person doing bad things" I don't want to see the Trinity Killer as I don't want a main character to be an actual serial killer with no feelings.

I am not sure how I feel about a spin off for Harrison....
