I agree about not needing the smaller depth of field. The current 60 f2.8 has a shallower DOF than lenses like the Olympus 45mm f1.8. On resolution charts it is just behind the Olympus 75mm. It barely seems worth making one, but they will primarily for Sony E mount. I was out last night with the Sigma 1.4 and it was great, but 60 1.4 would probably have been a bad choice for street/casual shooting as everything except your subject will be out of focus, making it a specialist portrait lens.
I guess the most important factor will be what focal length the Sony people want. A quick search shows there is a Sony 50mm f1.8 already, which is only $250. It gets amazing reviews too. But possibly not much else with autofocus or fast aperture. So 50mm seems a weird choice.
Here in M43 land people seem to like 90mm or 85mm eq best (42.5 or 45mm), so maybe it will be another 60mm to make a 90mm eq for Sony. They seem to have a lens that is 85mm f1.8 so 60 seems a decent inbetween.
I hope they then move on to smaller (than the 18-35 and 50-100) fast zooms. A smaller version (with M43 mount) of their 50-100 would probably be better than the forthcoming prime.
My ideal next prime from Sigma would be a 35m ff eq for Sony, which would be 23mm giving us a nice inbetween the 16 and 30, plus a faster focusing alternative to the Panny 20mm. Almost a M43 45mm equivalent. I dont think the Sony apsc e mount has such a lens so it makes sense to me with 35mm being such a classic focal length.
