I received this response from them today:
"The next generation of PTR-32 rifles chambered in 7.62x39 will function with a variety of steel AK mags, as well as a variety of polymer magazines. It will be impossible to guarantee that ALL steel mags will work... but most will. PTR is planning on bringing this product back to the market some time the in the first quarter of 2013."
Considering not all AKs work with all AK mags, I'm happy with this. This rifle will replace my AK.
