It seems like the next logical step. They better, I mean HTC's One has it's "ultrapixel" sensor + OIS now.
But this is the essential problem with Windows Phone, Microsoft being so damn slow.
I mean Nokia made the focking amazing 41MP oversampling sensor over a year ago for 808 PV Symbian, but it needed to fit a lot of specialized software that fit the algorithms to handle the complex task of oversampling the 41MP sensor and forming 38MP, 8MP, 5MP or 3MP photos. It also needed Nokia to fit another GPU that's in the sensor module working as a first puffer to take some tasks away from the main GPU.
Can Nokia do that in Windows Phone? It can't in the current slow pace of supported SoC's, screen resolutions stuck to the max on Lumia 920 and in general poor hardware flexibility. Windows Phone needs faster movement in hardware and it isn't coming before Microsoft provides the support and flexibility. Thing is it seems like Microsoft wont have any kind of event in MWC concerning Windows Phone so we are not getting those updates. You wont just suddenly see new SoC and screen resolution in Windows Phone device, Microsoft first needs to announce it supports it, like it has done with all of the other versions.
That to me means definite no for any kind of true PureView phone or major jump in hardware in MWC.
