I saw this article on ONTD (the source is at the bottom of the page) and thought y'all might be interested. I normally try not to believe in gossip (usually gossip is just that), but somehow I'm inclined to believe this.
Please be forewarned that there could be a tiny (casting) spoiler for 50th anniversary special (if you're avoiding all spoilers), but if you're like me (i.e. a total spoilewhore), the casting is something we've already known.
Here's the link to
the ONTD post and
here's a link to the actual source.
