Yes, in Japan, they never have the actual consoles on the floor. They do have lots of display boxes on the floor, but that is not what my picture above is of. It is "Take-to-the-till" boxes that do go back out onto the floor. However, the actual stock in a store would be greater than the number of "Take-to-the-till" boxes on the floor. The Joshin store above also had a massive mountain of actual PS4 boxes (yes, with the handle) behind the counter.
Naturally, anecdotal evidence is not the whole picture, but if I can go in to a total of five different stores late on launch day and the day after launch and all of them have stock, that doesn't look great. Of course, without knowing the allocation, this can mean any number of things.
