Usually it's Sony with the E3 announcement leaks, but a Dutch site has outed one of Nintendo's. According to N1ntendo, they have an E3 appointment for a Castlevania game for the 3DS. The game, subtitled Mirror of Faith, is scheduled to be revealed at E3. The appointment also mentions that David Cox, who worked on Lords of Shadow, is involved.
Why a gaming site would publish their E3 appointment schedule for the vultures at NeoGAF to find is beyond me, and I'm curious if the appointment will suddenly be canceled. You're kind of supposed to keep that info under wraps to prevent such leaks, but I guess we all know how many people care about respecting other people's wishes.
Soooo, Castlevania on 3DS. Interested?
