The French magazine Focus Numerique interviewed Sigma CEO Mr. Kazuto Yamaki. To read the french article you have to pay a fee (which I did). And I have some good news to report:

1) In future Sigma will develop new lenses designed exclusively for Sony FE cameras: “We will develop native optics for Sony FE if they are different from what we can already offer in our “reflex” range.”

2) Sigma plans to offer more of their current DSLR lenses with native E-mount. Also future new DSLR lenses will be immediately available for E-mount too.

3) The current new FE lenses are completely new from a software point of view. To write software for prime lenses is easier. But Sigma plans to release native E-mount zoom too (SAR note: expect an FE version of lenses like the 24-70mm ART for Canon).

4) About the current new FE primes: Sigma says that even if they had redeveloped these fixed focal lengths for the Sony FE mount, they would have arrived more or less on the same kind of optical design and especially the same type of weight and size. The only exception is for wide-angle lenses which could be much more compact.

To sum up:

All current and future DSLR lenses will be made available as native E-mount option (this includes zooms)

Some of their future lenses will be designed purely for Sony FE cameras (particularly wide angle lenses)
