I prefer to see the glass as half full and be happy of the possibility to mount the mighty ART 85/1.4, 105/1.4 & 135/1.8 with native high speed AF instead of with the slow MC-11 adapter.
As the size of the Sony Zeiss/GM 35/1.4, 50/1.4 & 85/1.4 is similar to the Sigmas, I'm not sure if a redesign from Sigma would be worth the efforts.
The case of the 14, 20 & 24mm is more disappointing but there are already many e-mount alternatives for wide angles.
That's probably the safest approach if you shoot static or slow moving objects.
In my experience, AF-C was not reliable past 3fps with the MC-11 adapter. I guess the protocol conversion introduces some lag in the communication between the camera and the lens.
For the e-mount lenses, Sigma claims to have licensed the protocol from Sony and that the lenses are compatible with high speed AF.
