The Resident Evil series numbers are adding up, which is awesome, and we all know our main characters. One character that has been mainly a side character and IS my favorite, is Ada Wong. I hope in the near future a sequel comes out with Ada as the main character. It can even go into her personal life and her work as a spy; for that we're "not sure if that's her real name" (records). Don't even know her age either. This idea could greatly please Ada fans and it has to include Leon and maybe a few others
However, coming off of RE6, the story line(s) are increasing as well with multiple characters and it can include intersections and clarification of Carla & Ada to Chris.
