The new 180mm Sigma looks pretty...

The 19mm e-mount is also very interesting. That's the focal length very close to where everybody's aunt is using her superzoom 95% of the time. So it will be popular. I will get one for sure, especially considering the EX label.

It looks like Sony isn't the only one to re-use (without proper editing) old merchandising material now and again. At least as it's quoted on SAR, the press release for the 19mm claims to be equivalent to a 38mm on a full-frame. That would be true on a 4/3rds camera, but on a NEX (APS-C sensor) it's equivalent to ~28-29mm (i.e., as we all know, they have a factor of 1.5x, not 2x).

The press release for the 30mm seems to have the same mistake (claiming it gives the FoV of a 60mm on a full frame).

You noticed too, makes you wonder does it not...

& unless I'm mistaken it's a 150mm OS HSM Macro that's coming in A-mount (already out in CaNikon mounts) & the Sigma 50 is a 1.4 not 1.5 ...
edit :I see that Sigma do seem to have announced a 180/2.8 Macro but currently Japanese & US Sigma websites (it's not on UK) only mention Sigma mount - not even CaNikon let alone A-mount.
