The headline grabbing Lumia 920 model will cost around €599 (£475) according to Nokia's Italian office, reports say, although it has also been announced by Nokia Germany as €649.
While Nokia could not, or would not confirm UK pricing to me, I have been reliably informed that it is likely to be closer to Italian pricing, so, somewhere around £475 SIM-free. Naturally, I also expect it to be free on qualifying contract deals when it's available on EE's network.
The slightly lower-specced (but in some ways, preferable) Lumia 820 is listed as coming in at €499 (in both Germany and Italy) meaning it should make its way to the UK for something like £395 if SIM-free.
The pricing of the 920 puts it in direct competition with premium handsets like the iPhone 5 and Samsung Galaxy S3. However, the S3 still costs around £450 (despite being on the shelves for around 3 months) and the freshly-released iPhone 5 pricing starts from £529, rising to £599 for the equivalent 32GB model.
