Literally all of this could have been said 20 months ago.
Nothing has changed. Which is worrying. There are no "recent indications that work and progress have been accomplished". You say there are, but there aren't. Name me one thing the company has confirmed that has happened recently (within the last 6 months) that indicates we are any further along right now than we were 6 months ago. You can't. You can only speculate.
