If by “confirmed” you mean maybe, the NiGHTS is already in development for Wii and is coming soon!

Quick News – Following years of speculation, it has finally been confirmed that a brand new NiGHTS from Sega is coming to Nintendo’s Wii. Whilst both companies refuse to comment at present, Spong has it on good word that is definitely in progress right now.
Spong and “fact” go together like oil and water, so let’s see what happens. This and the Official Nintendo Magazine teaser lead me to believe this rumor has more weight than most, but again, ONM is the Perrin Kaplan of game magazines, or so I’ve heard.
