I've spent the last day or so trying to get orders in, impeded by my Australian-ness (apparently some international sites don't like my cards!), and while I managed to get an order in on Best Buy for a 32GB model it's showing that it'll ship in "null - null days", which I don't consider promising - so if anyone managed to pick up a spare of either size and would be willing to sell it for cost-ish + tip (shipping to US or Australia), please let me know - I'll definitely be interested if my BB order doesn't go through!
(I've now had about 6 orders fall through >_
