In all seriousness she would probably play like MVC3 deadpool type character who has great zoning and ranged combos while also being able to rush-down with melee focus combat as well. She is probably undoubtely being worked on as we speak as not only did they hint at her being high on the list during early S3 development but they also put her in the survey.
I either expect her to be in the game as some sort of bonus character by the end of the year or announced at the World Cup.
