Just to add a little from another area:
Here in Holland, retailers don't have stock. Apparently, they all just got one shipment at launch, and the second isn't due until January at least (some are even saying April, but that's probably a conservative estimate). All their websites are saying "Our first shipment of PS4 has sold out...". Even for big players like Media Markt.
Dutch online stores also do not appear to have stock, they probably also got just the one shipment. Amazon UK seems to have some stock, but not much while the other European Amazones we here use (DE and FR) don't have stock at all.
A Dutch site similar to Craigslist, has a couple second-hand PS4's on offer for well over the standard €399. However, they don't have much responses and it's impossible to verify is something has actually been sold. Dutch eBay, which automatically lists offerings from Holland and it's neighboring countries (Germany, Belgium, Luxembourg, France and the UK) similarly has a couple overpriced second-hands. They mostly seem to sell for high prices, with this Killzone-bundle in Germany selling for €750
Going by the state of stock in retailers and the second-hand offerings, I'd say demand hasn't yet been satisfied here in The Netherlands, possibly due to the low shipment we have been getting, and I gather the rest of Europe would be a similar situation.
