Yeah, recently covered it in this thread on the Biotest forum. Creatine malate was discontinued, not exactly sure why though. I was using it myself for the longest time too.
Like anything in the product line (actual products, particular flavors, or whatever), it's usually either a matter of not enough people getting on board with it or it being shelved while something better is put together. I haven't heard about anything new in the works with the creatine, so the micronized monohydrate is the go-to for now.
