At least this date I make sure to remember so nothing catches me with my pants down, but December 28th, it always fucking gets me. I don't know who thought having a "Día de los inocentes" on December was a good idea, should've just stuck to April.
Nintendo owns Bayonetta 2 outright. WB retained ownership of LCU despite Nintendo publishing it, which is why it's now multiplatform (i.e. Nintendo's publishing contract expired). It's possible that Sega has purchased Bayonetta 2 from Nintendo, but I wouldn't consider it likely.
