Which guest fighter(s) should be in the next Soul Calibur

[Sensei]

I'm going with the obvious - Kratos on the PS3 version. Shame that Mortal Kombat took Kratos as a guest, I don't think it's going to be that great of a game...

What about Bayonetta on the 360 version. Sega could cooperate with Namco on that one. ;D
