When I first unveiled in December, 2010 that I received word on a Castlevania title in development for 3DS that would cleverly make use of the system's cameras, more so than the motion control inputs...it took a while before more news was found.
Ironically, this whole Star Fox - Metroid: Fusion Saga thing popped up on my desk just over a week before when I was planning to talk about Castlevania: Mirror of Fate.
To answer your question though, you will be seeing it at E3 this June and I apologize for being less than 100% honest with you in my reply a couple days ago. I did mention you, however, and this very topic in my article on the subject...as a bit of a shout out.
(This was the article you were originally referring to, correct?)
That being said, I hope you're satisfied now! And I'll end this with one question to all of you, "Would you rather the Wii U Castlevania game have continued to been Mirror of Fate or are you happy that it's turning out to be Lords of Shadows 2?"
