I think people will stop asking Chris Eccleston about Doctor Who after the 50th anniversary episode. It's an important event that will only come once. Eccleston just happens to be in the spotlight for another big production with Marvel at the same time DOTD is on peoples minds. That's why people are curious about his involvement in a show that most people recognize him for. After November though and when Capaldi takes up the reins for the show. I think people will stop asking Chris about DW.
