Chipworks found last year's "UltraPixel" cam to be a 4-megapixel affair. This revision likely has the same pixel count, but with larger pixels.

Much more interesting is the addition of this secondary rear camera, which in concert with the first enables all sorts of fancy image data manipulation, retroactive focusing, and special effects.

Not to be outdone, the intrepid selfie-cam gets a huge spec bump, leaping from last season's 2.1 megapixels to a whopping 5.0 MP (more than selfiesufficient).
