Real Talk: Why does US distribution suck?

The fact that the major stores and Hasbro have, street date breaking aside, managed to co-ordinate an actual launch date for AoE products just made me wonder why Hasbro can't be better about this at other times.
To give a comparison Takara has specific launch dates for every product, and only once in the five years I was there did I see a example of a distribution flub (something went wrong with the launch of NEST Brawn, Mindwipe and Skystalker). The figures appeared on shelves on that set date, and in reasonable numbers.
Admittedly Japan is far smaller than the US so physical distribution is a far simpler prospect but I have no idea why Hasbro can't at least get CLOSE to that level of efficiency. Why is there no real indication on when figures will show up? Why do some waves almost slip under the radar only to show up later at discount while others turn up in bulk.
I understand that part of it is the idea here in the US that stores have a lot more control over what shows on shelves. But surely it doesn't do the stores any good to still have 20 Beast Hunters Huffer clogging up shelves.
