Viewers have been waiting for an end to Aaron's suffering following his struggle with his sexuality, his decision to help paraplegic boyfriend Jackson Walsh (Marc Silcock) commit suicide and a subsequent obsession with self-harming.
In a teaser video of the next year, Blackburn said that while there may still be hardship ahead for Jackson's mother Hazel (Pauline Quirke), Aaron will finally experience "a ray of sunshine" ahead of his departure from the village.
"Hazel and Aaron's [assisted suicide] story has been magnificent and what can I say about Danny Miller and Pauline Quirke? They are absolutely phenomenal," he said.
"I think Hazel is going to make the ultimate sacrifice. What we're going to see with Aaron is perhaps finally, a real ray of sunshine, a real chance for him to find happiness. It's whether he's got the courage to actually go for it and take it."
However, Blackburn also forecast a bleak 2012 for Aaron's relatives in the Dingle family, hinting that they will face their "biggest challenge" yet in the coming months.
