It will be released when it's released. Hippomaster has a life outside of modding. All I can suggest is be patient. Pestering him to release the mod won't make him release it any faster and may well slow it's development.
I'd love to try it out. Got a working AnimationAPI download directly from Curse, and I can download the 1.7.2 Aquatic Abyss that way too, so my "unable to download from adf.ly" problem for the mods is solved ... but that only gets me 3/4 of the way there.
