For anyone still hoping/believing that Nibris' Sadness will ever see the light of day on the Wii, sorry. This just isn't your day. Seems that Frontline Studios, who were developing Nibris' "concept", may have parted ways with the Polish studio. When a Sadness "fan" emailed Frontline to see what was up with the game, he got this response:
Hello Ryan, I can confirm that FRONTLINE is no longer interested in developing Sadness game based on Nibris' concept, and also Nibris is not authorized to claim anything on behalf of FRONTLINE.
Sounds fair to me, since this "game" has never been anything but one enormous lie. No official confirmation from Nibris, but considering the level of info we're heard from them over the past 9 months I wouldn't expect any, either.
