I dont think so Nokia will be putting a 41mp camera in new phone.
phones such as 1020 1520 are niche devices, they need to gain market share,so they are keen on developing cheap and affordable phones,such as 520 620 720.
These devices did better everywhere specially 520.
In developing countries their are very few people who buy high end phones as they cost a bomb.
For my country India, 1020 costs more than 1520. Their are no carrier's or so so have to buy it at full cost.
The Idea of plonking 41mp sensor in a snap 800 seems great and everyone wants that but out their in real their will be very few people and few enthusiasts who will buy them.
Putting so much research and development costs a lot and time too. The original 808 took yrs to develop and perfect.
Nokia and Microsoft need more marketshare so the idea of 41mp in a plablet will take time, untill unless their is some new developments in camera dept.
I myself was in the same boat but then as a photography enthusiast went and got the 1020.
