Welcome to Muppet Wiki!
Again, if we specify the evidence in the article to the reader, I'm fine with it. But the casual reader won't read this discussion, and again, given past precedents, while it's definitely clear that Whitmire is focusing on Disney *now*, I don't think its wise for the article to imply "This means he has stopped playing Ernie in any capacity ever." (That's fine for fan speculation or discussion, but not encyclopedic.) A box is information, but it's not the only way to present the info, and by itself, not always the best way.
Also as currently structured, the casting section is pushed down in the article, so a short summary would help (including specifics such as the 2012 Whitmire performance, etc.) I'll try to work on it myself when I have time.
