See http://magazine.magix.com/en/sound-forge/ for the roadmap Sound Forge family, upcoming releases.
I read it here first. See also https://www.magix.info/us/audio-forum/
For those still interested in the Sound Forge family, there's a new version 12 of Sound Forge Audio Studio out. See http://www.magix.com/int/sound-forge-audio-studio/ and the forum link above.
I'm still interested and I find the new meters and the spectral cleaning great tools for such a low priced audio editor. I'll wait to see if there will be a Pro version later else I'll somewhen buy this Studio version. According to the roadmap the Pro version may be released late 2017 or 2018.
Perhaps we can guess that Sound Forge Pro 12 is very near, since the listing for SF Pro 11 says "Available until September 20, 2017" -- similar to the way they advertised Vegas Pro 14 just before 15 came out.

Still, it seems a shame to let people unknowingly buy the old version right up until the new version is available...
