No argument here about NP's lack of ability to manage expectations. I'd add his inability or unwillingness to acknowledge that his crusade for being an open book about what the Company is doing is NOT the same as openly expressing his hopes for what he expects to happen in some made guesstimated time frame.
Hence I say NP shouldn't say ANYTHING until he's got solid news to present. Don't do a cc just to tell investors "everything is OK, its just taking longer than he thought it would". To that last part I say "NO SHIT SHERLOCK!"
