Not likely, since the release of HG/SS is just a month or so before that. They'll probably release it sometime in the fall/start of the holiday season, similar to when SoA was released.
I don't use "uber" Pokemon , I don't calculate stat values, I don't use cheating devices, I don't breed my way to perfection, and I don't care about natures. I catch my Pokemon the way they are, and treat them like individuals instead of brainless drones. If you use this philosophy, copy & paste this into your signature. (Started by Tyranitar)
