There was an article I read earlier on them changing how they're PACKAGING PS4 shipments, not that they had problems with shipping times - that they're adjusting the packaging to make sure that they don't get damaged during shipping. (
Amazon ships replacement PS4 packaging - GeekWire) And she was talking about Wave 2 shipment that is starting to show up, not that there's leftovers from the Pre-Order Wave 1 - pretty sure I worded that clearly that this is in reference to a NEW WAVE not the original wave.
And note: while looking up that article (I'd seen it on the phone while in the waiting room for our therapist earlier) - there's other articles mentioning that allocation for the UK launch has extra units on Amazon.uk just as an interesting sidenote. (Don't think our Waves and theirs would coincide, being that whole ocean thing...)
(And ouch - they do have them available to order right this second on amazon.co.uk, but with shipping and currency conversion an extra $100 - cheaper than getting them from Craigslist though - but I'll hold on...)
