Remember the Grinder? It's still looking for a publisher as of now. But according to the Wikipedia page, The Grinder is set to be published by Warner Bros. Interactive. While this is hardly a reliable source, the publisher in question seems an odd choice for a hoax given High Voltage's history with SEGA. I actually contacted GoNintendo directly with this information, but they wanted to check with HVS first. However, there's been no news story on it. I don't know whether that means a flat denial by the guys at HVS, a generic 'no comment', or is HVS has not responded to contact. As such, I've decided to post the thing here (since it isn't doing any good in the C2 thread where I initially posted it) for you good people to discuss.
As far as we know, the Grinder is still set to release Halloween of this year (but I seriously doubt it's going to hit that mark. I still pray it's in development) for all systems.
