Sigma APO teleconverter EX DG discontinued?

Are the Sigma APO teleconverter 1.4x and 2x EX DG discontinued? I saw they were removed from Sigma Japan website.

Accessory - SIGMA CORPORATION

However, B&H and Adorama still have some in-stock. May be they are the last batch of the Sigma teleconverters, or hopefully Sigma will be releasing newly updated HSM-enabled version soon.

They're still showing up on their US website, but it would be nice if we saw one that was HSM-compatible (after all, they just need to run some wires).

there were some talk that they are replacing them due to compatibility issues.

If they adjusted the aperture and focal length while they were at it, I'd buy one of each before the day was out.

Yes, I would pick one within a heartbeat too!

Sigma really need to upgrade their APO teleconverters to support HSM (SDM) since all their new Pentax lenses are HSM enabled.
