In response to a question, "I don't want to bother you, but when do you think you are going do have a gameplay showcase ready for Bayonetta 3? I really want to see all the changes." (obviously from a foreign fan, from the google translate-esque Japanese). Kamiya said "Next week, on the game's website"
No word on how big said information will be, but we're going to know more within the week about Bayonetta 3 and if it'll actually be coming this year or not (though it should be noted that he's known for trolling so whether this is true or not remains to be seen..)
