Yeah, he seems to be embracing the idea of taking over the 3rd Doc role, something he said he'd never do. Maybe in a few years for the 60th they'll bring him in to play the 3rd Doctor. I'd love to see that year feature a number of specials, each one paying tribute to a different era of the show. I think it would be the best way to pay tribute to the series, as even though I though Day of the Doctor was good, it should have been so much more expansive than a short movie.
