Not for Pentax.
From the press release:

This new lens will be available at the end of April in Sigma, Canon and Nikon fit. Sony and Pentax will follow shortly.

The Pentax version will probably be available in May, but knowing Sigma it'll probably not be seen in any stores until late summer. The new 50-200mm that was released over a month ago still isn't available barely anywhere, and nowhere I've seen it for the Pentax mount yet. I hope that will change soon though since I want one of them.

that's ok. enough time to save money or contemplate on buying something else that comes out during that time.

Is there a good reason to get the Sigma over the Pentax 50-200? The Sigma costs more, weighs twice as much, is 30% longer, and the only feature it adds over Pentax is HSM. There does not seem to be a big difference in IQ (except, maybe, at 50mm), according to the only review I could find. For about the size and weight of the Sigma, it seems like the DA 55-300 makes more sense IMO.

Agreed. The Sigma 50-200 has got to be one of the least appealng lens releases in recent memory.

I have 10-20mm old version, but I use it 90% at 10mm, quality is decent. I listen the new model quality is better but I don't think there's this big difference,
if you fond old model at a good price, why not :->

I don't have Pentax right now, and for Canon which I do have, the Sigma is actually the most appealing option right now unless I went with the EF-s 55-250mm IS, which I had before and liked, but it costs a bit more new than the Sigma does. If I did have a Pentax though I would definitely go with the DA 50-200mm instead of it.

The price will probably be outrageous for the 8-16mm when it comes out. I would just get the 10-20mm 3.5

I checked one out for about a week before deciding on the Pentax DA 10-17 fisheye. I just got a K-x a few months back and if you don't mind the barrel distortion of a fisheye lens, it will offer you a much wider field of view than an ultra-wide like the Sigma 10-20mm lens. 180-100 degrees on the Pentax fisheye vs 102-63 degrees on the Sigma 10-20.

If you compse the shot correctly, you can really minimize the look of the distortion on the fisheye like so:



Of course, if you really want to get crazy with the fisheye, you can do that as well :
