When considering the overall size of lens and camera I'm struggling to see the allure of pancake design, especially with the existence of the significantly faster 35/2 and 50/1.8. Maybe the STM will find lovers in the video realm but for stills?
BTW, based on what is currently known, does anybody understands how STM is better than Ring-USM?

The STM is a must for fast live view contast AF. That is why all mirrorless cameras choose stepper motors over USM-style motors.
The 40mm f2.8 is still a lot more compact than the 35mm f2 and the 50mm f1.8. The 50mm f1.8 anyway is awful with its AF. The 35mm is noisy, and has 5 sided non-rounded aperture blades, the 40mm is better in that respect. It is also much cheaper.
Whether this pancake has the so-so bokeh of most other pancake lenses or not still has to be seen.
