I suspect that part of the issue is that folks jumped to buy this machine online and so all models produced are going to fill those orders before the stores get any. At least until the online gets down to the 1-2 weeks shipping time and then there might be some trickling of units out to stores. But it will likely go fast.
I would go ahead and place an order online now and if you can't have it shipped to the house or the office, set it for pickup at whichever store is best for you. There have been reports that sometimes these 4-5 week waits suddenly cut in half so it might not be that long. And if nothing else you'll get in before it can get any worse.
And look at the wait as a plus. It's not uncommon for the first couple of weeks to expose some goof in the machines that gets fixed for those latter shipments so you could be one of the folks that misses out on something nasty because you have to wait almost 2 months for your order to come up in the queue. Given how unfixable these machines supposedly are, I'd call that a good thing
