but whether it has 41 megapixels, 20 megapixels, or even 8-10-14 megapixels, pretty much all the high end Lumias have either thickness or camera bump due to its camera power..whether you have a 1020 or a 1520 or 830 or 930, you still get either a camera bump or thickness from the camera..so them making a separate phone to have the best camera still wont stop the main 2 phones from having camera bumps or thickness from that camera power..so I feel it's very unnecessary to have a separate phone for utmost camera power when you can just put it in the main flagship, and the main flagships larger sized phone.. besides the camera bump has easily become more than just a result of the camera having extreme internals stuffed in it.. It's become a super cool and notable Lumia design element!! that you get regardless of your cameras power, so no need to make a separate phone just to save non camera centric users from a tiny trim of camera size, when they ARE gonna get some form of camera bump either way
For the record, I have a 925 & 930... The 925 has a bump and larger lens but much lower MP for its camera... The 930 has a 20MP camera, smaller lens and no bump.
The 925 is thinner than the 930, but the 930 being thicker has little to do with the camera, and more to do with the wireless charging feature. The 925 can get an accessory which can give it wireless charging too, which then adds to its thickness.
The additional microphones on the 930 for the surround sound recording might also play a bit of a role.... But the camera in the 930 is not the primary factor for its thickness.
