Here are some images of Hex Stand first articles (the technical name for parts injected as tests of a new production mold during its development):



There are two different versions: one with two center solid studs and another with an addition two open studs on one side. Here's a CAD image of the design for the 4 stud version:

The mold is still in development while Will works with his tooler to ensure all of the fits are up the high-quality standards builders know to expect from him. As such, there's no set release date yet, but they are definitely coming.
One important note: while these stands were designed by Will, they aren't planned as an official part of the BrickArms line-up. Rather, they'll be available from Catsy, a name anyone in minifig customization is likely to be familiar with, via a website devoted to brick gaming he currently has in development. As more information is available, I'll be sure to post it here!
EDIT: Changed title to reflect the Hex Stands are a Catspaw Customs product
