It is very possible that they are just doing their best not to release another date that has to slip due to something unforeseen. They probably want the first production run not only complete, but in house and possibly even hand inspected just to make sure that when it does hit, it will be a hit. Its unfortunate that this can't be done on a 100% perfect schedule for anybody that wants one, but with the amount of grief they get every time a date changes, I wouldn't release another date until there was no chance for it to change.
After all, this really is a hobby and I know hobbies are pretty addicting and one of the best parts is a new piece of gear, of course. But if you're bored with your current system to such a point that waiting on a new product is going to kill you, then go buy something else. Or give your system the super tune, moving your speakers around to try and get better placement. Go play the speaker wire game, or make up a wireloom for the back of your rack. Something. There's got to be a better way to enjoy this hobby than driving yourself crazy waiting for something you have no control over.
You could always go watch a movie. I've heard there are a few good ones in the theaters right now.
