It's like a tease to a tease! Nintendo Life says Hideki Kayima made a statement proclaiming he is "thinking" about what he will do with Okami 2 and Bayonetta 3. This came as a shock to everyone including Microsoft and Platinum Games, who knew nothing about it prior to the interview. The exact quote is below...

GC: …I preferred Bayonetta's first haircut.
PR woman: [laughs]
HK: Then we will take that into account when we design her haircut when we start doing 3, if we ever make 3.
(The room is suddenly filled with gasps of shock, not just from us and the UK PR but also the other Microsoft and Platinum Games people.)
GC: Wha… what?! You can't tease me like that!
(Widespread laughter)
GC: Are you thinking of doing 3?
HK: Of course we want to make 3.
GC: [meekly] OK.
HK: Why should it end at 2?
GC: I don't think it should end at 2! Have you spoken to any publishers about this?
HK: No, but I've spent a lot of time thinking in my head what that game would be. I've got ideas in my head for Okami 2 as well.
Microsoft PR woman: What?!

I'm sure it's all just talk right now, but, of course, it's awesome to hear that both titles are up for consideration as his next projects!
