Marketing wise, the paucity of quality, native glass for the E/FE series
has done them no favours; especially when no one at Sony
ever gave a firm commitment to A-mount for (say) another 10 years.
They need to restablise their fan base, before disenfranchising them again.
They know it too, there seems to be a "full-time" offer of a
free lens adapter for every @7 sold to cover the obvious gap.
Curved is all very well, but unless it brings something
radically better to the table (like SLT), it will just be more tech.
Give the current, affordable, hammer blow of the @77Mk2, @99,
(and the 36mp @99Mk2 ?) plus all that A-mount glass,
it will be a very big call.
Tme to grow your market, Sony, not try to buy it (again).

Volunteer, what could possibly go wrong ?

I think the degree of curvature is specifically designed for the peripheral light loss of existing lenses. It doesn't mean that an entirely new lens system would be required. In fact, I'm sure that that's exactly what they are trying to avoid. There are certainly some business justifications for starting a new lens system (e.g. mirrorless systems that require much shorter lens register distances, or sensor formats of significantly different sizes), but I don't think a slight curvature of a sensor to compensate for light loss along the periphery of a sensor is one of them.

Plus, it could just be sensor to be used in a fixed lens camera, like future RX1 models.

I'm not sure that would work, current lenses are designed to have as flat a focal plane as possible and even the ones that don't all have different focal planes. You use them on a curved sensor and parts of the image are surley going to be out of focus?

I'm pretty sure this has been designed to save size on fixed lens cameras like the RX1, it might not even work on fixed zooms and shifting focal lengths might well shift the "easier" shape of the focal plane so again your needing to correct it with a larger design.

Well, I am not sure how a curved sensor fits into a interchangeable lens system, or even a fixed lens zoom camera.  What i am saying is that for cameras like the Fuji  x100s, the Nikon Coolpix A, or the Sony RX1 - fixed lens cameras with wide(ish) angle prime lenses - this could be a boon.  It could be very high IQ lenses in compact bodies.

For interchangeable lens systems - just a guess - but they would probably have to pick a curvature that is a compromise between wide, normal, and long focal lengths and design lenses around this curvature.  But still, it seems in a system like this, if they picked the curvature nicely, there would be a range of lenses the would benefit - like wide to normal range - and these lenses could be made with fewer elements (i.e. smaller and lighter).
