Large German retailer Media Markthas posted Lumia 920 and Lumia 820 to their site with November 1st release dates. Price for Lumia 920 is the Nokia suggested price for Germany at 649€ but interestingly 449€ for Lumia 820. That’s slightly less than Nokia suggested 499€ and to me much more closer to the mid level smartphone price range.
I would still be careful at reading too much into the date as Media Markthas could be just talking about November here without having any other info. Still Germany will very likely be one of the countries getting new Lumia’s on the very first day it’s available so time will tell.
