Lumia 920 has again gone out of stock in Germany. Situation is similar for all the operators and the page mentions that according to Nokia, no immediate shipping is possible and availability is from week 01, 2013 only. Only yesterday, it indicated wk 52 availability which seems that due to huge global demand has moved to wk 01, 2013.

Hopefully the issue is not just that Samsung and Apple are using all the components for themselves. I’d feel much better if these sold out reports were reports of high sales numbers.
Apple and Samsung have different components than Lumia in most of the cases. Also many carriers in many countries like Telstra, StarHub, AT&T, Tele2, Vodafone have confirmed huge demand.
