The producer of the Kingdom Hearts series Shinji Hashimoto revealed that there will be a new presentation for Kingdom Hearts at this year's Paris Games Week. The presentation will begin on Thursday at 7AM PST (10AM EST), and will take place after the Final Fantasy XV Presentation.
I think we might see some info for Kingdom Hearts III, but not a whole lot, because of what Tetsuya Nomura had recently said in a Famitsu interview that we wouldn't get more information until after the release of Kingdom Hearts HD 2.8: Final Chapter Prologue. So I believe we might get a little bit of info, and then they annouce the date for a huge Kingdom Hearts III event, or they might do what they did back at D23 event and just show off one of the new worlds that will be Kingdom Hearts III. But other than that I don't know what else they might show, because we've already seen so much of Kingdom Hearts HD 2.8 Final Chapter Prologue, so maybe some new info for Kingdom Hearts Unchained X.
