^ It sure as hell won't be called Eternal Darkness, since Nintendo own the rights to the Eternal Darkness brand (unless it is for Nintendo, of course). So you'll likely see a similar situation as Bioshock where they were forced to use a different name instead of System Shock.
yeah, i don't know if they'd be able to use the Alex Roivas character in the sequel, but they could always come up with an equally as cunning main character, something like Judith Niam Retcarahc.
not very true at all. the blog statement was the typical "we planed a whole universe around the game, so there's always more stories to tell and we'd love to tell them someday" stuff.
