"Planned Release" means that this game is in or near the Final stage and not in the "Early Access"/mostly playable Beta stage! Those downloading it should consider it as a Final or near Final "Release Candidate" of a game that may be worth looking into! For more information, see here.
The best news is that it's already here on IGG-Games.com!

There is full English support via the English interface, English audio and English subtitles!
