People always get use to the new thing. I mean shit, people for a long time wanted phones to get smaller and smaller. Now that they can watch netflix on them they want phones to get bigger and bigger. 
  
 I have no idea, but I bet the 3 camera thing drastically makes for better pictures. Insta-stars will be happy and then their followers will as well. Thus, the cycle will continue.

Yep. 3 cameras was unavoidable if they didn't want to get left behind when it comes to picture quality
