For all who said "L Lenses resolve such high resolutions": No they don't.
Lens Rentals has 2 awesome Articles, where they tested some Lenses at ultra high resolutions,
and only the sharpest Lenses you can get right now (eg Sigma 135mm, Zeiss Otus 85mm)
get in acceptable regions (purple line, 200lp/mm).
To go even further, they only get acceptable at this resolution stopped down, and only in the center of the
Image.
I'm quite sure you won't get much more sharpness out of a 150mpx sensor, but what you will get is more freedom
when editing the Image, and that's already an aspect i love about my 5DsR.
