Oh, Chris is fucking insane. Just not probably with anything diagnosable.
Agreed, publicly, it's less fixed. He's dropped some clues that it's imminent and specifically by the end of the year, but yeah, he's never said "100% by X date".
But privately he's been making a few statements and changing his behavior that doesn't make sense unless he thinks the current reality is going to end soon.
It's worrying. I don't think he won't do a 180% when that fails to happen, but it's going to be a really hard, uncomfortable 180 for him, both mentally and financially.
