News: Rogue One Writer Has Another Star Wars Idea

The writer and visual effects supervisor of Rogue One: A Star Wars Story John Knoll has another Star Wars idea.  According to THR, he told the attendees of the National Association of Broadcasters that the idea is still a work in progress:

“I have another idea I’ve been tinkering with, It’s maybe 75 percent there. I haven’t pitched it to [Lucasfilm president Kathleen Kennedy]. It’s another Star Wars thing.”

This is potentially exciting news, especially for fans that loved Rogue One. But it begs the question, why did he drop such secretive news when it hasn't even been pitched to Disney yet?
