This could be down to the either one of following: 
 

•  New Play Control Version
•  Protecting Brand 
•  Sequel in Development

If there is a sequel to this game, I may have to buy a Wii again.

I really don't see how Eternal Darkness would benefit from a "New Play Control" version regardless of whether we're talking gameplay or sales, so I'm betting it's either brand protection or an upcoming sequel. Really hope it's the latter.

Too bad Silicon Knights is too busy on... whatever the fuck they're doing. I'm thinking it's just to protect the brand.

David Ellis on some 1UP video said that an Etenral Darkness game was in production. But he was drunk. Coincidence though?

For all the excitement about the brand, I don't know if I would play another Eternal Darkness. I played the first game recently, and found it to be a somewhat clunky but still decent Action-Adventure game that you can totally tell was originally for the N64 with a sanity mechanic that becomes null and void once you learn the "Restore Sanity" Spell. Maybe it was awesome in 2002. I don't know.

Although I love Too Human I still haven't played this game. I should really get on that.

Considering Nintendo Patented the 'Sanity' System years ago, this could be a new game, but i'm thinking it will be one of those 'new play control' games. All i know is, Denis Dyack ain't touching this unless he removes himself from Microsoft (they ARE a 2nd party still right?)
